Quality Control

Our 2,3-Dimercapto-1-Propanol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing purity, physical properties, and test results is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). Due to its properties of being easily oxidized and light-sensitive, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents.
