Quality Control

Our Trithiomolybdic Acid is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance. Standard tests include assay, identification, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

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