Isobutanol (IUPAC nomenclature: 2-methylpropan-1-ol; also known as 2-methylpropyl alcohol, among other names) is a colorless, flammable, organic compound with a characteristic smell. Its isomers are 1-butanol, 2-butanol and tert-butanol.

The main use of isobutanol is as starting material in the manufacture of isobutyl acetate, which is mostly used in the production of lacquer and similar coatings. Isobutyl acetate is also used in the food industry as flavouring agent.

Isobutanol is a volatile, flammable, liquid that should be stored and used in well-ventilated areas. It is moderately irritating to the skin and greatly irritating to the eyes, mucous membranes and respiratory tract. Exposure to high concentrations of its vapour can cause temporary narcosis.

Alcohols can be used as a beverage (ethanol only), as fuel and for many scientific, medical, and industrial utilities. Ethanol in the form of alcoholic beverages has been consumed by humans since pre-historic times. A 50% v/v solution of ethylene glycol in water is commonly used as an antifreeze.

Alcohols can also undergo oxidation to give aldehydes, ketones or carboxylic acids, or they can be dehydrated to alkenes. They can react to form ester compounds, and they can (if activated first) undergo nucleophilic substitution reactions. The lone pairs of electrons on the oxygen of the hydroxyl group also makes alcohols nucleophiles. For more details see the reactions of alcohols section below.
