A Buyer’s Guide to 2-Bromopyridine-5-carbaldehyde CAS 149806-06-4: Identity, Specifications, and Sourcing

2-Bromopyridine-5-carbaldehyde, CAS 149806-06-4, is a brominated pyridine aldehyde used as a building block in chemical synthesis and research. Its structure combines a pyridine ring, a bromine substituent, and an aldehyde group, giving chemists multiple points for further transformation. The molecular formula is C₆H₄BrNO, and its calculated molecular weight is approximately 186.01 g/mol. For procurement, buyers should confirm identity, assay method, impurity information, packaging, and batch-specific documentation rather than relying on the name and CAS number alone.

Who This Guide Is For

This guide is intended for procurement teams, process chemists, medicinal chemistry groups, and distributors evaluating 2-Bromopyridine-5-carbaldehyde for a project or supply program. It is especially useful when comparing supplier quotations that may differ in stated purity, analytical evidence, pack size, or delivery terms. The recommendations below distinguish known identity information from specifications that must be confirmed with the supplier. They are not a substitute for reviewing the current product specification and certificate of analysis for a specific lot.

Identity and Basic Context

What the compound is

The product name identifies a pyridine ring bearing bromine at the 2-position and a carbaldehyde group at the 5-position. The aldehyde can serve as a site for reactions such as condensation or reduction, while the carbon–bromine bond may be used in suitable substitution or coupling chemistry. The feasibility and selectivity of any route depend on the reaction conditions and the rest of the substrate. Buyers should therefore match the material to a defined synthetic step rather than assume that one grade or batch will suit every use.

Useful calculated reference values

Based on the molecular formula C₆H₄BrNO, the calculated molecular weight is approximately 186.01 g/mol. On a theoretical basis, 1 g corresponds to about 5.38 mmol before accounting for assay, moisture, or other impurities. These values can help with initial stoichiometric planning, but actual weighing calculations should use the lot assay and the project’s handling procedures.

Specifications to Review Before Purchase

There is no single universal specification that buyers should assume from the compound name alone. A supplier’s offer should state the grade or purity target and explain how identity and assay are assessed. Ask for a current, lot-specific certificate of analysis when available, and check that the product name and CAS number match the requested material. If your project has limits for particular impurities, residual solvents, water, or metals, specify them before quotation rather than assuming they are covered by a general purity statement.

Match the Material to the Application

For early-stage route exploration, buyers may prioritize availability of a small evaluation quantity and sufficient analytical information to confirm suitability. For a later-stage synthesis, the key questions may shift toward reproducibility, impurity control, and the supplier’s ability to support repeat orders. In either case, a material that meets a nominal purity target is not automatically suitable if an impurity interferes with the next reaction or complicates purification. Share the intended use at an appropriate level of detail so the supplier can respond to the requirements that matter.

Plan quantities using project needs

When requesting quotations, consider comparing clearly defined quantities such as 1 g, 10 g, and 100 g, where relevant to your project. These are example request sizes for evaluating price breaks and logistics, not a statement of stock availability or a supplier’s minimum order quantity. If you are scaling a route, calculate the required amount from the planned batch size, stoichiometry, expected process losses, and assay. This avoids buying solely on a unit-price comparison that may not reflect the usable quantity required.

A Practical Supplier Selection Framework

Evaluate more than the quoted price

Compare offers on a like-for-like basis: same requested quantity, specification, packaging, delivery destination, and documentation. A lower price may not represent better value if the quote excludes required analysis, uses a different purity basis, or has uncertain lead time. Ask whether the quoted material is available from stock or is subject to production, and request the expected dispatch window in writing. Treat delivery estimates as supplier-provided planning information, not a guarantee unless the terms explicitly make them one.

Supplier evaluation checklist

• Does the quotation identify the compound by both name and CAS number?
• Are purity, assay method, and the applicable batch clearly stated?
• Can the supplier provide lot-specific analytical documentation for review?
• Are the offered pack size, packaging details, and shipping terms suitable for your handling requirements?
• Are MOQ, stock status, lead time, and quote validity stated rather than implied?
• Can the supplier discuss specification alignment or repeat-order requirements before you commit?

Pricing, MOQ, and Lead Time

Price, minimum order quantity, and lead time can vary with requested quantity, specification, packaging, stock position, and destination. They should be confirmed for the actual order rather than inferred from a general product listing or an earlier quotation. For a meaningful comparison, provide the desired quantity, target purity or assay, destination, and any documentation requirements in the same inquiry. If your schedule is fixed, ask the supplier to distinguish estimated preparation time from transit time.

Common Purchasing Mistakes to Avoid

One common mistake is treating the CAS number as complete evidence of batch quality. It supports product identification, but it does not by itself establish the assay, impurity profile, or suitability of a particular lot. Another is comparing prices without checking whether the quoted quantities and specifications are equivalent. Buyers can also overlook shipping and documentation requirements until after the order is placed, which may introduce avoidable delays.
