Quality Control

Our Dimethyl Mercaptosuccinate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets precise customer requirements and internal specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents and bases. Due to the presence of a thiol group, it is recommended to store under an inert atmosphere for long-term stability.
