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 1-undecanal, the analogous aldehyde.^[2]

Natural occurrence

1-Undecanol is found naturally in many foods such as fruits (including apples and bananas), butter, eggs and cooked pork.^[3]

Toxicity

Undecanol can irritate the skin, eyes and lungs. Ingestion can be harmful, with the approximate toxicity of ethanol.^[4]
