Quality Control

Our tert-Butyl 1,1,3,3-Tetramethylbutyl Peroxide is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay and purity verification by GC, to ensure it meets precise specifications for use as a polymerization initiator. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep container tightly sealed and separate from incompatible materials such as reducing agents, strong acids, and bases. Recommended storage temperature is 15-25°C. Due to its nature as a strong oxidizer, handle and store with appropriate precautions to prevent decomposition.
