Quality Control

Our production of Benzoyl Chloride, 3-Chloro-4,5-Dihydroxy- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive synthetic applications. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We support cGMP and ISO 9001 compliant manufacturing practices, and specifications can be tailored to meet specific project requirements.

Storage

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