Quality Control

Our tert-Butyl 2,2-Dimethylperoxybutyrate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay and impurity profiling, to meet stringent industry specifications. A Certificate of Analysis (COA) detailing purity, active oxygen content, and safety parameters is provided with every shipment to guarantee compliance with your process requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Keep away from incompatible materials such as strong acids, reducing agents, and heavy metal compounds. Due to its nature as a strong oxidizer, store separately in a dedicated, temperature-controlled environment (recommended below 25°C/77°F).
