Quality Control

Our Benzoyl Chloride, 3-Formyl-4-Hydroxy- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Store away from strong acids, bases, and oxidizing agents.
