Hazard Information

General Description
Clear colorless liquid.
Reactivity Profile
The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. DI-TERT-BUTYL PEROXIDE is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 1979v.
