Quality Control

Our Glycol Dimercaptoacetate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identity confirmation (IR), and impurity profiling, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee consistency and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is light-sensitive and easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve stability and prevent degradation. Keep away from strong oxidizing agents, strong acids, and strong bases.
