Quality Control

Our 1,1,2,2-Tetrachloroethanesulphenyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC/HPLC and identity confirmation by FT-IR and NMR, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are provided to guarantee compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its nature as a strong acid/organic solvent and highly volatile compound, it should be kept away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C for extended stability. Keep container tightly sealed when not in use to prevent moisture ingress and volatilization.
