Quality Control

Our Cyclobutane Malonyl Peroxide is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, activity, and stability. Certificates of Analysis (COA) documenting key parameters such as assay, active oxygen content, and impurity profiles are available upon request to support your quality assurance protocols.

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 a peroxide and being light-sensitive, it should be kept separate from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is between 2°C and 8°C to maintain stability. Always refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
