To source 4-Pentylbenzeneboronic acid CAS 121219-12-3 reliably, I recommend confirming the chemical identity first, defining the required grade and quantity, requesting lot-specific documentation, and evaluating the supplier’s ability to support both small research orders and scale-up requirements. At Maison Chemical, I treat the process as a technical procurement decision rather than a simple price comparison. The target compound is an aryl boronic acid used as a building block in synthetic research, so identity, purity, handling, packaging, and continuity of supply should all be reviewed before purchase.

Before contacting suppliers, I recommend writing a short purchasing brief for 4-Pentylbenzeneboronic acid CAS 121219-12-3. The brief should state whether the material is intended for route scouting, medicinal chemistry, process development, pilot work, or repeated bulk synthesis. It should also identify the initial quantity, expected annual demand, required delivery location, packaging preference, and documentation needed by your laboratory or quality team.
This step prevents a common sourcing problem: asking for “high purity” without defining what that means for the project. A research laboratory may begin with a gram-scale evaluation, while a process team may require hundreds of grams or more after route confirmation. These requirements can involve different packaging, production planning, analytical review, and commercial terms.
| Item | Reference Information | Why It Matters |
|---|---|---|
| Product name | 4-Pentylbenzeneboronic acid | Helps distinguish the target from related aryl boronic acids and boronate esters. |
| CAS number | 121219-12-3 | Provides an additional identity check during quotation and documentation review. |
| Calculated molecular formula | C11H17BO2 | Useful for reviewing molecular-weight calculations and analytical records. |
| Calculated molecular weight | Approximately 192.07 g/mol | Supports reaction calculations, inventory planning, and solution preparation. |
The formula and molecular weight above are calculated reference values and should be checked against the supplier’s current product documentation. I advise buyers to ensure that the product name, CAS number, structure, and analytical description are consistent across the quotation, specification sheet, SDS, label, and certificate of analysis. If any document uses a different synonym or describes an ester rather than the free boronic acid, clarification should be obtained before ordering.
4-Pentylbenzeneboronic acid is an aryl boronic acid that can serve as a synthetic building block in research and development. Its boronic acid functionality is relevant to coupling and derivatization strategies, while the pentyl-substituted aromatic structure may be selected when a hydrophobic alkyl group is required in the target molecule. The exact suitability depends on the reaction design, substrate compatibility, solvent system, catalyst, temperature, and downstream purification method.
For early research, the buyer may prioritize availability, practical packaging, and sufficient purity for screening. For bulk synthesis, the purchasing decision should place greater emphasis on lot-to-lot consistency, impurity control, packaging integrity, reproducible analytical data, and the supplier’s ability to plan repeat production. I recommend discussing the intended reaction stage with the supplier without disclosing confidential route details that are not necessary for quotation.
Buyers should clearly distinguish 4-Pentylbenzeneboronic acid from the corresponding pinacol ester or other protected boronate derivatives. These materials are related, but they are not automatically interchangeable in procurement, weighing, reaction calculation, or process performance. A supplier quotation should state the exact requested form, and the delivered label should match that form.
Boronic acids can also be sensitive to storage and handling conditions depending on their structure and formulation. I therefore recommend asking about the supplier’s recommended storage conditions, packaging configuration, retest or review information when available, and any known handling precautions. The laboratory should follow the current SDS and internal chemical safety procedures rather than relying on general assumptions about boronic acids.
A professional quotation should be supported by documents that allow the buyer to evaluate identity and quality before committing to a larger order. At a minimum, I suggest requesting a product specification, SDS, and lot-specific certificate of analysis when available. For a qualification project, representative HPLC, NMR, GC, water, residual solvent, or other data may be useful, but the relevant tests should be agreed according to the compound and application.
The certificate of analysis should be reviewed for product name, CAS number, lot number, test date, test methods, specification limits, actual results, and authorized approval. A purity value should not be considered meaningful without knowing the analytical method and reporting basis. If a buyer requires a particular method or impurity threshold, that requirement should be stated before production rather than after delivery.

When I evaluate a supplier for 4-Pentylbenzeneboronic acid, I compare technical responsiveness, documentation quality, quotation clarity, and supply continuity alongside price. A low unit price may not represent the lowest total procurement cost if the material requires additional testing, arrives in unsuitable packaging, or creates delays during project transfer. Buyers should compare equivalent grades, quantities, Incoterms, packaging, analytical scope, and delivery assumptions.
Three commercial details require particular attention: MOQ, lead time, and forecast demand. A supplier may quote a different price for a research pack, a custom batch, and a recurring bulk order. I recommend requesting at least two quantity tiers, such as a laboratory quantity and a scale-up quantity, while confirming that the quoted specifications remain comparable.
| Decision Area | Questions to Ask |
|---|---|
| MOQ | What is the minimum order quantity for stock, sample, and production supply? |
| Lead time | Is the quoted delivery window based on available stock or new manufacturing? |
| Packaging | Can the package size and protection method support the intended storage period? |
| Export service | Can the supplier provide commercial documents and shipment coordination for the destination country? |
For a research order, I usually recommend keeping the first purchase technically focused and easy to evaluate. For a bulk-synthesis program, I recommend starting qualification before the pilot campaign is complete, because procurement lead time and analytical approval can affect the next production stage. The buyer should define acceptance criteria internally and record any approved deviations rather than relying on informal email discussions.
One frequent mistake is confusing the CAS number with a guarantee of quality. The CAS number helps identify the intended substance, but it does not by itself establish purity, water content, residual solvents, physical condition, or suitability for a particular reaction. Another mistake is accepting a generic “research grade” description without requesting the actual specification and lot documentation.
Buyers also sometimes compare quotations that are not technically equivalent. For example, one offer may include a lot-specific COA and export documentation while another may exclude testing, packaging, or shipping-related charges. A further risk is ordering a large quantity before checking whether the material performs acceptably in the buyer’s specific reaction system.
At Maison Chemical, I support buyers by organizing the sourcing discussion around identity, quantity, documentation, delivery, and future demand. We can review requests for 4-Pentylbenzeneboronic acid CAS 121219-12-3 for research quantities as well as larger synthesis programs, subject to current manufacturing and supply conditions. Our role is to help the buyer receive a clear commercial proposal that can be reviewed by purchasing, laboratory, quality, and logistics teams.
For projects requiring additional evaluation, I recommend sharing the required specification, target quantity, destination, preferred delivery schedule, and documentation checklist at the quotation stage. This allows us to clarify whether the request can be supplied from available material or requires production planning. Any custom analytical or packaging requirement should also be discussed before order confirmation.
The most reliable way to source 4-Pentylbenzeneboronic acid CAS 121219-12-3 is to verify the exact chemical form, define application-specific requirements, review lot-level documentation, and qualify the supplier before moving from research scale to bulk synthesis. Price is important, but it should be compared with purity documentation, packaging, lead time, communication quality, and continuity planning. This approach reduces the risk of receiving a technically unsuitable or poorly documented material.
As a next step, prepare your requested quantity, purity target, destination, packaging preference, delivery window, and documentation requirements. Send these details to Maison Chemical for a structured quotation and supply discussion. We can then help determine the appropriate procurement route for your research, process-development, or bulk-synthesis program.
