Quality Control

Every batch of 4-tert-Butylperoxy-6-Chloro-2-Methyl-Pyrimidine is manufactured and tested under strict quality management protocols to ensure consistency and reliability. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request 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 a strong oxidizer, store separately from reducing agents, combustible materials, and acids. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, although short-term storage at controlled room temperature (15-25°C) may be acceptable. Always refer to the Safety Data Sheet (SDS) for complete handling and storage instructions.
