For any chemist, formulator, or procurement specialist in the chemical industry, understanding the technical specifications of a compound is fundamental to its successful application. This is particularly true for intermediates like 4-Chloro-2-nitrobenzonitrile (CAS 34662-32-3), where precise parameters dictate its suitability for various synthesis processes.

The primary specification for 4-Chloro-2-nitrobenzonitrile is its purity, typically required to be ≥99.0% or higher. This high assay ensures that the compound will behave predictably in reactions, minimizing the risk of unwanted by-products and maximizing the yield of the desired product. For pharmaceutical and agrochemical synthesis, this level of purity is non-negotiable. A clear appearance, such as 'White Powder,' is also a basic indicator of quality and consistency.

Beyond purity, other critical parameters often include 'Loss on Drying' (typically ≤2.0%), 'Heavy Metals' (often ≤10 ppm), and 'Water' content (often ≤1.0%). These specifications are crucial for certain sensitive applications where even small amounts of moisture or metallic contaminants can interfere with reaction chemistry or degrade the final product. For instance, in API synthesis, trace metals can affect catalyst performance or lead to undesired side reactions.

Understanding these technical details allows buyers to make informed decisions when selecting a supplier. When you inquire about purchasing 4-Chloro-2-nitrobenzonitrile, asking for detailed specifications and Certificates of Analysis (CoA) is a standard practice.
