If you are sourcing Pyridine-3-boronic acid CAS 1692-25-7, you should evaluate more than the chemical name and quoted price. This heteroaryl boronic acid is commonly considered as a building block for carbon–carbon bond formation, especially in Suzuki–Miyaura coupling research and pharmaceutical or agrochemical intermediate synthesis. At Maison Chemical, I recommend confirming identity, assay, physical form, packaging, documentation, and delivery expectations before placing a purchase order.

Pyridine-3-boronic acid is generally represented by the molecular formula C5H6BNO2, with a calculated molecular weight of approximately 122.92 g/mol. Its CAS Registry Number is 1692-25-7. Because boronic acids can be sensitive to storage and handling conditions, the appropriate grade and supply format should be selected according to the intended reaction, development stage, and quality-control requirements.
This guide is intended for procurement teams, research chemists, process-development groups, contract manufacturers, and distributors evaluating Pyridine-3-boronic acid for laboratory or commercial supply. It is also useful when comparing several organic boronic acid suppliers and deciding which documentation should be requested before technical approval. I focus here on practical purchasing factors rather than presenting an unverified performance guarantee.
The best product choice depends on the application. A small research project may prioritize pack size and rapid availability, while a scale-up program may require batch consistency, production planning, traceability, and a clear specification agreement. These requirements should be discussed with the supplier before the quotation is treated as technically comparable.
Pyridine-3-boronic acid is an organoboron compound containing both a pyridine ring and a boronic acid functional group. The pyridine nitrogen provides heteroaromatic character, while the boronic acid group can participate in palladium-catalyzed cross-coupling reactions with suitable electrophilic partners. In practical synthesis planning, its value comes from combining a pyridyl fragment with a reactive boron-containing handle.
The “3-” designation identifies the position of the boronic acid substituent on the pyridine ring. This positional difference matters because 2-, 3-, and 4-pyridyl boronic acids are not automatically interchangeable in reaction design. I therefore advise buyers to verify the exact isomer, CAS number, molecular formula, and structure before approving a substitute.
The most relevant use case is as a heteroaryl boronic acid coupling partner. In a suitable Suzuki–Miyaura reaction, the boronic acid fragment can be combined with an aryl or vinyl halide, triflate, or another compatible electrophile to form a new carbon–carbon bond. Actual conversion depends on the catalyst, base, solvent, temperature, substrate structure, concentration, and work-up procedure, so supplier material should not be treated as a guaranteed solution for every reaction.
Pyridine-containing structures occur in many areas of medicinal and crop-protection chemistry. Pyridine-3-boronic acid may therefore be evaluated during the preparation of substituted biaryl or heteroaryl intermediates. Its suitability should be assessed through route-specific screening, particularly where catalyst poisoning, boron speciation, solubility, or purification are important concerns.
At early development stages, buyers may use this material for reaction scouting, analog generation, and route comparison. During process development, the focus normally shifts toward reproducibility, impurity control, material balance, and scale-appropriate packaging. I recommend aligning the requested specification with the stage of the project instead of paying for requirements that are not connected to the intended use.
| Specification Area | What to Confirm | Why It Matters |
|---|---|---|
| Identity | Product name, CAS 1692-25-7, structure, and molecular formula | Prevents confusion with another pyridyl boronic acid isomer |
| Assay or purity | Test method, reporting basis, and batch result | Supports reaction planning and batch comparison |
| Physical form | Powder, crystalline solid, color, and visible condition | Helps define handling and incoming inspection |
| Water or solvent content | Whether moisture or residual solvent is tested | May affect weighing, reaction concentration, and storage |
| Documentation | Certificate of analysis, SDS, lot number, and packing details | Supports quality review and traceability |
The stated molecular weight of approximately 122.92 g/mol is useful for stoichiometric calculations, but it does not replace a batch-specific certificate of analysis. Buyers should also ask how assay is determined and whether the reported value is on an “as-is” basis or corrected for water and residual solvent. If the material is intended for a regulated or tightly controlled process, the internal specification should be agreed before production.
Start by identifying the exact coupling partner, catalyst system, base, solvent, and target scale. This information helps determine whether standard research material is sufficient or whether additional controls on moisture, metals, or specific impurities are needed. I recommend sharing a concise technical requirement rather than requesting only a generic price.
Verify that the supplier is quoting Pyridine-3-boronic acid and not a related compound such as pyridine-2-boronic acid, pyridine-4-boronic acid, or a protected boronate ester. The free boronic acid and an ester may have different handling, solubility, and reaction behavior. The CAS number, structure, formula, and product label should agree across the quotation and quality documents.

For screening work, a defined assay range and basic identity documentation may be adequate. For process work, you may need tighter impurity limits, consistent analytical methods, controlled packaging, and retention samples. I can help organize these requirements into a practical specification for supplier review without assuming that one grade fits every project.
Before committing to a larger quantity, request a representative sample when appropriate and review the available certificate of analysis. Compare identity data, assay, appearance, water content if relevant, and test dates. A single sample result does not prove long-term batch consistency, so repeat supply should be supported by an agreed quality and communication process.
The price of Pyridine-3-boronic acid can vary according to quantity, grade, testing requirements, packaging, production route, and availability. A quotation without a stated quantity and specification is difficult to compare fairly. Buyers should ask whether the offer is for a stocked quantity, a scheduled production batch, or a custom manufacturing arrangement.
Minimum order quantity is also supplier- and project-dependent. Smaller quantities may be suitable for research, while larger orders may require production scheduling and advance confirmation of packaging. Lead time should be requested in calendar days or weeks, with the supplier clearly stating whether it begins after purchase-order confirmation, payment, technical approval, or sample approval.
For international procurement, I also recommend confirming shipping classification, package labeling, export documents, storage instructions, and the destination country’s import requirements. These details can affect the effective landed cost even when the product price appears competitive. Maison Chemical can review the requested quantity, destination, documentation needs, and target delivery schedule when preparing a B2B quotation.
A reliable supplier should communicate limitations as well as capabilities. For example, the supplier should not claim that a material is suitable for every synthetic route without reviewing the chemistry. I prefer a transparent technical exchange in which the buyer and supplier define the required tests, acceptance criteria, and delivery conditions before the order is finalized.
One frequent mistake is selecting a product solely by CAS number and price while ignoring isomer, assay basis, or physical form. Another is assuming that a catalogue specification automatically matches a process specification. Buyers also sometimes request a large quantity before confirming that the material performs acceptably in their specific coupling system.
Storage and documentation are additional areas that deserve attention. The receiving team should follow the supplier’s SDS and label instructions, keep the container properly closed, and assess whether moisture exposure could affect the planned use. If a project has strict impurity limits, those limits should be stated in writing rather than inferred from a general purity description.
At Maison Chemical, I approach Pyridine-3-boronic acid sourcing as a technical and commercial process. We can discuss the required quantity, intended application, packaging preference, documentation, target destination, and expected delivery window before preparing a quotation. This helps reduce ambiguity between research-grade purchasing and process-oriented procurement.
Our role is to provide clear product identification and practical supply communication, while the buyer remains responsible for confirming application suitability through its own evaluation. For repeat or larger-volume requirements, I recommend establishing a documented specification and reviewing each batch’s accompanying quality information. This approach gives procurement and technical teams a more reliable basis for approval.
The right way to buy Pyridine-3-boronic acid CAS 1692-25-7 is to match the material specification and supply conditions to your actual synthetic objective. For routine research, identity, assay, documentation, pack size, and availability may be the main priorities. For process development or commercial manufacturing, batch consistency, impurity control, packaging, traceability, and delivery planning become more important.
As your next step, prepare the required quantity, target specification, application stage, destination, and documentation expectations. Send these details to Maison Chemical for a focused B2B discussion and quotation. I will help clarify the available supply option while keeping the final technical approval based on your own reaction and quality requirements.
