Quality Control

Our Chloromethyl Methyl Carbonate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments to verify compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening. Recommended storage temperature is 2-8°C for long-term stability.
