Quality Control

Our Dihydroxysulfur is produced and tested under stringent quality management systems. We ensure batch-to-batch consistency through rigorous analytical protocols, including chromatographic purity assays and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee compliance with your research or production specifications.

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 area. Due to its sensitivity to oxidation and reactivity with strong acids and organic solvents, it should be kept isolated from incompatible materials. Recommended long-term storage temperature is 2-8°C.
