Quality Control

Our 2-Ethylacryloyl Chloride 99 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC and NMR, to ensure a minimum purity of 99% and conformity to specified impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistent quality for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
