Quality Control

Our Potassium tert-Butyl Peroxide is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, activity, and stability. We provide detailed Certificates of Analysis (COA) with each shipment, documenting key parameters such as assay, active oxygen content, and impurity profiles. Our commitment to consistent quality and supply reliability supports your critical production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), it is recommended to store the material under an inert gas (e.g., nitrogen or argon) in a moisture-proof environment. Maintain storage temperature between 2°C and 8°C for extended stability. Isolate from incompatible materials such as strong acids, reducing agents, and flammable substances.
