Quality Control

Our 1,2-Dichloro-1-(Methylsulfonyl)Ethene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing including HPLC, GC, and NMR to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) to minimize moisture uptake and degradation. Recommended storage temperature is 2-8°C for long-term stability.
