3-Ethyl-3-pentanol, also known as 3-ethylpentan-3-ol, is a tertiary alcohol with the molecular formula C<sub>7</sub>H<sub>16</sub>O.
It reacts with chromic acid by first dehydrating to an olefin 3-ethyl-2-pentene, and then by converting the double bond to an epoxide.
Perfluorination affords perfluorotriethylcarbinol, a powerful uncoupling agent.
