Quality Control

Our 1,1-Bis(Methylthio)Ethane is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. A Certificate of Analysis (COA) detailing specific results for identity, assay, and impurity profiles is provided with every shipment to guarantee it meets your precise technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
