Quality Control

Our Dichloroethyne is manufactured under stringent quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and Infrared Spectroscopy (IR) to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with every shipment to support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and reactive nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition and maintain stability. Recommended storage temperature is 2-8°C for long-term stability.
