Product Description
Tert-Butyl Hydroperoxide (TBHP), also known as tert-butyl hydroperoxide, is an organic peroxide with the molecular formula C₄H₁₀O₂. Depending on its concentration and grade, it is typically supplied as a colorless to pale yellow liquid. It has limited solubility in water and is soluble in many organic solvents, including ethanol and ether.
TBHP is widely used as an oxidizing agent and free-radical initiator in chemical synthesis and selected industrial processes. It can be used in certain oxidation reactions and polymerization systems, with specific applications depending on the formulation and process requirements. Its role in bleaching, deodorizing, cross-linking, or rubber vulcanization should be confirmed against the relevant product specifications and technical documentation.
