Quality Control

Our Bis(1-Methylpropyl) Peroxide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by GC or titration and impurity profiling, to ensure it meets exacting purity and performance standards. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment to guarantee supply reliability and product consistency for your industrial processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and strong oxidizing nature, it must be kept separate from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is 2-8°C (35-46°F) to maintain stability and shelf life. Always handle in accordance with local regulations for organic peroxides.
