Quality Control

Our Trimethylolethane Tri-(3-Mercapto Propionate) is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay and impurity profile analysis, to ensure it meets precise specifications for industrial and research applications. A Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is available for every shipment upon request.

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 easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve product integrity. Keep away from strong oxidizing agents and bases.
