Molecular Weight: 146.23 g/mol
Chemical Formula (CH3)3-COOC-(CH3)3 or C8H18O2

Di-tert-butyl peroxide or DTBP or Tert-Butyl peroxide is an organic compound consisting of a peroxide group bonded to two tert-butyl groups. It is one of the most stable organic peroxides. Di-Tert-Butyl Peroxide or DTBP is used to as a catalyst of polymerization for olefin copolymers and cross linking agent for unsaturated polyesters. It is also used as a fuel additive and chemical intermediate. It is a strong free radical source containing more than 10.9% of active oxygen. It decomposes rapidly, causing fire and explosion hazard, on heating and under influence of light. Highly flammable. Refrigerate.
