Quality Control

Our sec-Butylidene Hydroperoxide is manufactured under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including assay by iodometric titration and impurity profiling, to ensure it meets precise specifications for purity and stability. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality 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. Due to its nature as a strong oxidizer and highly volatile compound, it must be segregated from reducing agents, acids, bases, and combustible materials. Recommended storage temperature is 2-8°C (35-46°F) to maintain stability. Keep container tightly sealed when not in use to prevent evaporation and decomposition.
