Quality Control

Our production of Benzoyl Chloride, 4-Methoxy-2,5-Dimethyl- (9Ci) adheres to stringent quality management systems. Every batch is subjected to comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide full traceability and detailed Certificates of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our commitment to cGMP principles ensures reliability for critical applications in regulated industries.

Storage

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