For any procurement professional or R&D scientist, understanding the specifications of chemical compounds is the first step towards making an informed purchasing decision. When it comes to 2-(Chloromethyl)benzonitrile (CAS 612-13-5), a crucial intermediate in organic synthesis, several key parameters define its suitability for industrial applications. This guide provides a breakdown of what buyers should look for when they intend to buy 2-(chloromethyl)benzonitrile.

Purity (Assay): This is arguably the most critical specification. For 2-(Chloromethyl)benzonitrile, a purity of ≥99% is generally considered standard for most pharmaceutical, agrochemical, and fine chemical applications. Higher purity ensures fewer side reactions, better yields, and a cleaner final product. A reputable manufacturer will always provide a detailed Certificate of Analysis (CoA) stating the precise assay. Always verify this before committing to a purchase, especially when sourcing from a new supplier.

Appearance: The typical appearance of high-quality 2-(Chloromethyl)benzonitrile is a white powder. Any deviation from this—such as discoloration or the presence of foreign particles—could indicate contamination or improper storage. While visual inspection is a good initial check, it should be complemented by analytical data from the CoA.

Melting Point: The melting point range is another important indicator of purity. For 2-(Chloromethyl)benzonitrile, the specified range is usually between 56-61°C. A narrow melting point range close to the literature value suggests a highly pure substance. A broad or significantly lower melting point range often points to the presence of impurities.

CAS Number and Chemical Name: Always confirm the CAS number (612-13-5) and the correct chemical name, 2-(Chloromethyl)benzonitrile. Synonyms, such as 2-Cyanobenzyl chloride, are also common, but it’s essential to cross-reference these with the CAS number to avoid confusion. Working with a supplier that clearly identifies the product by its CAS number provides an extra layer of certainty.

Packaging and Storage: While not a direct quality metric of the compound itself, how it is packaged and recommended storage conditions are indicative of a supplier's professionalism. Typically, it is supplied in drums (e.g., 25kg/drum) and should be stored in a cool, dry, well-ventilated area, away from heat and ignition sources, and kept tightly closed. Understanding these requirements helps in maintaining product integrity post-delivery.
