Quality Control

Our Benzoyl Chloride, 4-Methoxy-2-Methyl- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for fine chemical and pharmaceutical-grade intermediates. 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 must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability.
