Quality Control

Our Benzoyl Chloride, 2,3,5-Trimethyl- is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity, consistency, and traceability. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage. Recommended storage temperature: 2-8°C for optimal stability.
