Quality Control

Our Benzoyl Chloride, 3-Chloro-5-Methoxy- (9Ci) is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing including HPLC, GC, and NMR to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specification parameters. Our quality commitment aligns with cGMP principles where applicable, ensuring reliability for critical synthesis steps.

Storage

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