Quality Control

Our 3-Chloroperoxybenzoic Acid is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay and impurity profile analysis, to ensure it meets the high-purity standards required for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and stability data is provided with every shipment to guarantee traceability and consistency for our B2B partners.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place, away from heat sources and incompatible materials such as strong reducing agents, bases, and heavy metals. Due to its nature as a strong oxidizer and being strictly light-sensitive, it should be handled with appropriate care and stored separately from flammable or combustible materials. Recommended storage temperature is 2-8°C for long-term stability.
