Quality Control

Our 2,3-Dimercaptopropionic Acid is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for industrial and research use. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its properties of being easily oxidized and highly volatile, minimize exposure to air, heat, and moisture. Keep away from strong oxidizing agents.
