Quality Control

Our (R*,S*)-Monohexyl 2,3-Dimercaptobutanedioate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets precise customer specifications and high-purity standards. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, enantiomeric ratio (if applicable), and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended long-term storage temperature is 2-8°C. Due to its sensitivity to oxidation, the container should be purged with inert gas after each opening to maintain product integrity.
