Quality Control

Our Benzoyl Chloride, 3-Ethenyl- is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by HPLC and impurity profiling, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment and are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (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) to prevent hydrolysis. Keep away from strong bases, oxidizers, and sources of ignition.
