Quality Control

Our Bis(3-Thienylcarbonyl) Peroxide is manufactured under strict quality management protocols. Each batch is analyzed to ensure it meets precise specifications for purity, reactivity, and stability. Certificates of Analysis (COA) documenting key parameters such as assay, peroxide content, and impurity profiles are provided to guarantee consistency and support your quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures typically between 15-25°C. Keep away from heat, sparks, open flames, and incompatible materials such as reducing agents, strong bases, and heavy metal salts. Due to its nature as an organic peroxide and being easily oxidized (store under inert atmosphere), handle and store with appropriate precautions to prevent decomposition.
