Quality Control

Our 5-Mercapto-1,2,3-Thiadiazole Sodium Salt Dihydrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to minimize exposure to moisture and air.
