Quality Control

Our production of this organic peroxide adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm critical parameters such as active oxygen content, assay, and solution concentration. Certificates of Analysis (COA) detailing purity, assay, and solvent content are provided with every shipment. We support compliance with relevant global safety and transportation regulations for peroxide formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Due to its nature as an easily oxidized (store under inert atmosphere) and highly volatile material in solution, containers must be kept tightly sealed and handled with appropriate precautions to prevent peroxide concentration.
