Quality Control

Our 2-Chloropropionyl Chloride is manufactured under stringent quality management systems. Every batch undergoes rigorous analytical testing, including assay by GC or titration and impurity profile analysis, to ensure it meets high-purity standards suitable for sensitive synthesis applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific tests is provided with each shipment to guarantee traceability and consistency for our global B2B clients.

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 such as strong bases, alcohols, and amines. Due to its highly volatile and hygroscopic nature, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for extended stability.
