Undecanol is a colourless, water insoluble liquid of melting point 19 °C and boiling point 243 °C.
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.
1-Undecanol is found naturally in many foods such as fruits (including apples and bananas), butter, eggs and cooked pork.

Uses

1-Undecanol has a floral citrus like odor, and a fatty taste and is used as a flavoring ingredient in foods.
1-Undecanol is commonly produced by the reduction of 1-undecanal, the analogous aldehyde.
