Natural Product Identification
Common NameOctanol
Description1-Octanol, also known as octan-1-ol, is the organic compound with the molecular formula CH3(CH2)7OH. It is a fatty alcohol. Many other isomers are also known generically as octanols. Octanol is mainly produced industrially by the oligomerization of ethylene using triethylaluminium followed by oxidation of the alkylaluminium products. This route is known as the Ziegler alcohol synthesis. Octanol also occurs naturally in the form of esters in some essential oils. Octanol and water are immiscible. The distribution of a compound between water and octanol is used to calculate the partition coefficient (logP) of that molecule. Water/octanol partitioning is a good approximation of the partitioning between the cytosol and lipid membranes of living systems. Octanol is a colorless, slightly viscous liquid used as a defoaming or wetting agent. It is also used as a solvent for protective coatings, waxes, and oils, and as a raw material for plasticizers. It is also one of many compounds derived from tobacco and tobacco smoke and shown to increase the permeability of the membranes of human lung fibroblasts (PMID 7466833 ).
