Quality Control

Our production of Tetrakis(2-Methylbutyl) Thioperoxydiphosphate adheres to stringent quality management protocols to ensure batch-to-batch consistency and reliability. Each lot is analyzed to confirm identity, purity, and key physical parameters. Certificates of Analysis (COA) documenting these results are provided and can be tailored to meet specific customer requirements or internal specifications.

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). This material is easily oxidized and should be kept under an inert atmosphere (e.g., nitrogen) for long-term storage to maintain efficacy. Keep away from strong oxidizing agents and heat sources.
