Quality Control

Our tert-Butyl Hydrogen Peroxymaleate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by titration and impurity profiling, to ensure it meets precise specifications for purity and performance. Certificates of Analysis (COA) documenting identity, purity, and relevant physical parameters are available for every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) at temperatures between 2°C and 8°C to maintain stability and prevent decomposition. Keep away from incompatible materials such as strong reducing agents, bases, and heavy metal salts.
