Tert-Butanol CAS#75-65-0
tert-Butanol (TBA), also referred to as trimethylmethanol or 2-methyl-2-propanol, is one of the four isomers of butanol, together with n-butanol, isobutanol, and sec-butanol. In its pure state, TBA appears as a colorless crystal and is a weakly polar small-molecule organic compound. When a small amount of water is present, it becomes a colorless, volatile liquid with a camphor-like odor. TBA is hygroscopic and flammable, with relatively higher toxicity and anesthetic effects compared with other alcohols. It is soluble in most organic solvents and is widely applied in various fields, mainly serving as a gasoline additive, solvent, and raw material for organic synthesis.
