Quality Control

Our production of Benzoyl Chloride, 3-Cyano-4-Methyl- adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, IR and NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets precise customer specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and amines.
