1-Nonanol/ˈnoʊnənɒl/ 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.
Various esters of nonanol, such as nonyl acetate, are used in perfumery and flavors.
More common than 1-nonanol are its many isomers, including isononyl alcohol, which are typically produced by hydroformylation of octenes.
These alcohol mixtures are used as solvents in paints and as precursors to plasticizers.
