Quality Control

Our 2-Hydroxyethyl Mercaptoacetate is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. Certificates of Analysis (COA) detailing the results of tests such as assay, impurity profile, and physical characteristics are provided and available upon request to support your quality assurance protocols.

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). Due to its property of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep away from strong oxidizing agents, strong acids, and strong bases.
