Quality Control

Our 2,3-Butanedithiol is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets exacting standards for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, this product should be stored in a cool, well-ventilated place, away from heat sources and oxidizing agents. Recommended storage temperature is 2-8°C for extended stability. Keep the container tightly sealed under an inert gas blanket (e.g., nitrogen or argon) to minimize oxidation and moisture ingress.
