Quality Control

Every batch of Benzoyl Chloride, 4-Chloro-2-Hydroxy- (9Ci) is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the precise requirements of your synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, and custom specifications can be developed to support your cGMP or research-grade applications.

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, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
