Quality Control

Every batch of Benzoyl Chloride, 4-(Propylthio)- (9Ci) is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the compound meets the exacting standards required for research and commercial synthesis. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment to guarantee traceability and consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature and classification as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
