Undecanol, also known by its IUPAC name 1-undecanol or undecan-1-ol, and by its trivial names undecyl alcohol and hendecanol, is a fatty alcohol. Undecanol is a colorless, water-insoluble liquid of melting point 19 °C and boiling point 243 °C.

Industrial uses and production

It has a floral citrus like odor, and a fatty taste and is used as a flavoring ingredient in foods. It is commonly produced by the reduction of undecanal, the analogous aldehyde.{{cite book
