2Methyl2butanol

2-Methyl-2-butanol, also known as tert-amyl alcohol or TAA, is a tertiary alcohol with the chemical formula C5H12O. It is a clear, colorless liquid with a characteristic camphor-like odor. This compound is miscible with many organic solvents, including ethanol and diethyl ether, and is slightly soluble in water. It is produced commercially through the hydration of amylenes.

Industrially, 2-methyl-2-butanol has found applications as a solvent, particularly in the pharmaceutical and chemical industries. It is used as a solvent for resins, oils, and waxes. It also serves as an intermediate in the synthesis of other organic compounds. Historically, it was used as a sedative and hypnotic, though this use has largely been superseded by safer alternatives due to its potential for adverse effects. It can be found naturally in some fermented beverages, albeit in small quantities.
