If I were qualifying 2-(4-Fluorophenyl)-thiophene, CAS 58861-48-6, for research, process development, or commercial sourcing, I would not rely on the product name alone. I would confirm the CAS number, molecular identity, lot-specific purity, analytical data, SDS, packaging, and supply terms before placing an order. The commonly associated molecular formula is C10H7FS, with an approximate molecular weight of 178.23 g/mol; however, I recommend verifying these details against the supplier’s current technical documentation. Maison Chemical can support this review by discussing specifications, COA requirements, SDS documentation, samples, and bulk supply options.

I prepared this guide for procurement teams, medicinal and process chemistry researchers, quality managers, and companies evaluating a new pharmaceutical or fine-chemical intermediate supplier. It is especially relevant when a project requires a defined aromatic thiophene building block rather than a general catalog material. The guide focuses on practical qualification questions instead of making unsupported claims about a specific batch or application outcome.
Buyers may use this material during route scouting, intermediate synthesis, structure-activity research, or development of fluorinated organic compounds. The exact suitability depends on the customer’s reaction system, impurity tolerance, scale, and regulatory requirements. For that reason, I recommend treating supplier information as one part of a broader technical and quality review.
2-(4-Fluorophenyl)-thiophene is an aromatic thiophene derivative containing a fluorinated phenyl group. Its identity is generally described through the chemical name, CAS 58861-48-6, molecular formula, molecular weight, structural representation, and analytical profile. These identifiers should appear consistently across the quotation, specification sheet, COA, SDS, label, and shipping documents.
The approximate molecular weight of 178.23 g/mol is useful for reaction calculations, theoretical yield estimates, and inventory planning. I still advise buyers to confirm the value shown on the supplier’s documents because naming conventions, rounding, and database records can differ. A structure file, such as an approved drawing or SMILES representation, can also reduce the risk of purchasing a positional isomer or incorrectly labeled analog.
Purity is usually the first commercial specification reviewed, but the reported number is meaningful only when the analytical method is understood. I ask whether purity is determined by HPLC, GC, or another method, and whether the result is area percentage, weight percentage, or a different basis. A buyer should also ask whether the COA lists known impurities, residual solvents, water, inorganic residues, and any relevant starting materials.
Do not assume that a high assay automatically meets every process requirement. A reaction may be sensitive to a trace positional isomer, residual solvent, water content, or catalyst poison. If the customer has a defined internal limit, I recommend sending that requirement to Maison Chemical before quotation so the specification can be assessed realistically.
The requested physical form should be confirmed rather than inferred from the product name. Depending on manufacturing conditions and temperature, an organic intermediate may be supplied as a solid, low-melting material, or liquid, and the appearance recorded on a COA should be lot-specific. Buyers should request information on color, odor where relevant, melting or boiling behavior if tested, and recommended storage conditions.
The SDS is essential for laboratory and warehouse planning. I review its hazard classification, handling precautions, personal protective equipment, spill response, fire response, transport information, and waste guidance. If the SDS does not answer a site-specific question, I recommend obtaining clarification before the material enters the facility.
A useful COA should identify the product name, CAS number, lot or batch number, test date or release information, analytical results, specification limits, and approval or authorization details. I compare the lot number on the COA with the package label and shipping documents. I also check whether the test methods are named clearly enough for my quality team to understand what has actually been measured.
For an efficient review, I use three consistency checks: identity consistency, specification consistency, and lot traceability. Identity consistency means the name, CAS number, formula, and structure do not conflict. Specification consistency means the quoted requirements match the COA limits. Lot traceability means the certificate applies to the material being shipped rather than to a generic reference batch.
I compare the SDS product identifier with the quotation and COA before approving a purchase. Important sections include composition, hazard identification, first-aid measures, accidental release measures, handling and storage, exposure controls, physical and chemical properties, stability, toxicological information, transport, and disposal. The absence of a hazard classification should not be interpreted as proof that the substance is harmless; workplace controls should follow the SDS and local requirements.
When importing or distributing the material, I also confirm whether the SDS format and language meet the destination market’s requirements. Shipping classification may depend on the available hazard data, packaging, quantity, and transport mode. Maison Chemical can discuss the available documentation, but the final compliance decision should be made by the buyer’s qualified regulatory or EHS team.
With competitive price and timely delivery, Maison Chemical sincerely hope to be your supplier and partner.
For early research, buyers may prioritize identity confirmation, sufficient purity, a small evaluation sample, and fast technical communication. For process development, the focus usually expands to impurity control, reproducibility between lots, packaging suitability, and the ability to provide representative samples. For commercial production, supply continuity, change-control communication, quality agreements, and shipment documentation become more important.
I recommend separating “must-have” requirements from “preferred” requirements. Must-have items may include the correct CAS number, an approved analytical method, a defined minimum assay, acceptable impurity limits, and an SDS suitable for the receiving site. Preferred items may include a specific packaging configuration, additional analytical data, a retained sample policy, or customized release testing.
Before requesting a quotation, I prepare a short specification brief covering the chemical identity, target purity, impurity concerns, required test methods, packaging, estimated annual demand, and destination country. If the final process has a narrow impurity tolerance, I include that information rather than asking only for a catalog price. This allows the supplier to evaluate whether the requested material can be supported consistently.
I request a current specification sheet, an example or representative COA, the current SDS, packaging information, and a statement of available manufacturing or supply status. A representative COA is useful for initial review, but it is not a substitute for the final lot-specific COA. If the product is critical to the route, I also ask about analytical method transfer, retained samples, and deviation or change-notification procedures.
Price should be evaluated together with minimum order quantity, sample availability, lead time, production scheduling, payment terms, packaging, freight, and import responsibilities. I avoid assuming that the lowest quoted unit price is the lowest total procurement cost. A supplier that can communicate clearly, provide consistent documents, and support scale-up may reduce avoidable qualification and resupply risk.
MOQ and lead time should be confirmed for the exact requested grade and destination, because they can vary with stock position, batch size, packaging, and production planning. I recommend requesting a written quotation that states validity, Incoterms where applicable, available quantity, estimated lead time, and document package. For a first evaluation, a 100 mg to 1 g sample may be appropriate depending on the customer’s test plan, but the required amount should be agreed with the supplier.
One common mistake is comparing products only by assay percentage without reviewing the analytical basis and impurity profile. Another is accepting a generic SDS or an old COA without confirming that the documents correspond to the supplied lot. Buyers also sometimes overlook the difference between research-scale availability and dependable bulk supply.
I also advise against specifying an unrealistically narrow requirement before discussing manufacturability. If a customer requires an assay threshold such as 98.0% or higher, that threshold should be linked to the intended process and verified by the agreed test method. The supplier and buyer should confirm whether additional purification, special packaging, or extra testing would affect cost and lead time.
At Maison Chemical, I approach this product as a technical sourcing discussion rather than a simple price request. I can help organize the review around identity, specification, COA, SDS, sample quantity, packaging, MOQ, lead time, and intended use. Where a customer has internal quality requirements, I encourage early communication so the proposed supply route can be evaluated before commercial commitment.
For bulk inquiries, I recommend sharing the target quantity, delivery location, preferred packaging, required documents, and project stage. This information helps distinguish a laboratory sample request from a development or production requirement. Any final specification, availability statement, and delivery schedule should be confirmed in the formal quotation and order documentation.
The right way to buy 2-(4-Fluorophenyl)-thiophene CAS 58861-48-6 is to qualify both the material and the supply process. I would begin by defining the required purity and impurity limits, then compare the supplier’s COA, SDS, analytical methods, packaging, MOQ, lead time, and commercial terms. This approach gives procurement, R&D, and quality teams a shared basis for an informed decision.
If you are evaluating 2-(4-Fluorophenyl)-thiophene for a sample, development batch, or bulk requirement, contact Maison Chemical with your target quantity, destination, specification, and document requirements. I can then help clarify the available supply option and identify the information needed for a responsible technical and commercial review.
