Quality Control

Our Benzoyl Chloride, 3,5-Difluoro-4-Methyl- (9Ci) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing all specifications are provided and 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 and reactivity as a strong acid/organic solvent, it must be kept under an inert atmosphere (e.g., nitrogen or argon) and separated from bases and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability.
