2-Hexanol (hexan-2-ol) is a six-carbon alcohol in which the hydroxy group (OH) is located on the second carbon atom. Its chemical formula is C<sub>6</sub>H<sub>14</sub>O or C<sub>6</sub>H<sub>13</sub>OH. It is an isomer of the other hexanols. 2-Hexanol has a chiral center and can be resolved into two different enantiomers.
Its toxicity is based on metabolism to hexane-2,5-dione.
