Quality Control

Our Benzoyl Chloride, 4-Methoxy-3-Methyl- is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistency. Certificates of Analysis (COA) detailing specific batch results are available upon request. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis. Keep away from strong bases, oxidizing agents, and sources of ignition.
