Quality Control

Our 3,3'-Dichlorodibenzoyl Peroxide is manufactured under strict quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed to confirm critical parameters such as active oxygen content and purity. A comprehensive Certificate of Analysis (COA) detailing assay results, identification, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat, sparks, and open flames. Due to its nature as an organic peroxide, it must be segregated from reducing agents, acids, bases, and other incompatible materials. Recommended storage temperature is 2-8°C (35-46°F) to maintain stability. Handle and store only in original containers.
