Quality Control

Our Tetraisobutyl Thioperoxydiphosphate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, purity verification, and impurity profiling. A Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, open flames, and incompatible materials.
