Quality Control

Our Potassium 2,3-Dimercaptopropanesulphonate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration, identification by IR spectroscopy, and impurity profiling, to ensure it meets high-purity standards suitable for research and industrial applications. A comprehensive Certificate of Analysis (COA) documenting purity, physical properties, and safety data is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at a controlled room temperature (15-25°C). Minimize exposure to air and moisture during handling to maintain product integrity.
