For professionals in the chemical and pharmaceutical sectors, the quality of raw materials and intermediates directly dictates the success of their projects. When sourcing 4-(Aminomethyl)benzonitrile hydrochloride (CAS 15996-76-6), a crucial intermediate for anilines, aromatic amines, and nitro compounds, understanding and verifying its quality is paramount. This detailed look into quality assurance aims to equip B2B buyers with the knowledge to make informed purchasing decisions.

The primary indicator of quality for 4-(Aminomethyl)benzonitrile hydrochloride is its assay, or purity level. Reputable manufacturers typically offer this white crystalline compound with an assay of 99.0-101.0%, with common results showing 99.8%. A higher assay signifies fewer impurities, which is critical for avoiding unwanted side reactions and ensuring the desired yield and purity in downstream syntheses. When you 'buy' from a trusted 'manufacturer', you can expect detailed Certificates of Analysis (CoA) that clearly state these purity levels, often determined by HPLC (High-Performance Liquid Chromatography) or titration.

Beyond assay, the physical properties provide further insights into quality. The appearance of 4-(Aminomethyl)benzonitrile hydrochloride is consistently described as a 'white crystal'. Any deviation from this can indicate potential contamination or degradation. The melting point is another key parameter; a sharp and consistent melting point range, such as 274℃-279℃ (lit.), suggests high purity and homogeneity. A broad or shifted melting point can be a red flag for impurities. For businesses looking to 'purchase' this intermediate, confirming these physical characteristics with the 'supplier' is essential.

Storage and handling also play a significant role in maintaining the quality of 4-(Aminomethyl)benzonitrile hydrochloride. As a chemical supplier, we ensure that our products are stored in cool, dry, and well-ventilated warehouses, away from incompatible materials. Proper packaging, often in 25kg drums, protects the product during transit and storage. When evaluating a '4-(aminomethyl)benzonitrile hydrochloride supplier', inquire about their storage conditions and handling procedures to guarantee product integrity upon arrival.

In summary, robust quality assurance for 4-(Aminomethyl)benzonitrile hydrochloride (CAS 15996-76-6) involves scrutinizing its assay, physical appearance, and melting point, alongside the supplier's storage and handling practices.
