1-Nonanol

1-Nonanol is a straight chain fatty alcohol with nine carbon atoms and the molecular formula CH3(CH2)8OH. It is a colorless oily liquid with a citrus odor similar to citronella oil.

Nonanol occurs naturally in orange oil. The primary use of nonanol is in the manufacture of artificial lemon oil. Various esters of nonanol, such as nonyl acetate, are used in perfumery and flavors.

Nonanols
More common than 1-nonanol are its many isomers, including isononyl alcohol, which are typically produced by hydroformylation of octenes. Isomeric octenes are produced by dimerization of butenes. These alcohol mixtures are used as solvents in paints and as precursors to plasticizers.

Toxicity
The LD50 (oral, rats) is about 2.98 g/kg.
