Quality Control

Our Benzoyl Chloride, 2-Hydroxy-3,5-Dimethyl- (9Ci) is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available upon request, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
