Quality Control

Our Tridecyl 3-Mercaptopropionate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay, purity verification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) documenting identity, purity, and key physical-chemical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong acids, oxidizing agents, and incompatible organic solvents.
