Metabolite Identification
Common Name3-Methylbutyl octanoate
Description3-Methylbutyl octanoate, also known as isoamyl caprylate or isopentyl octanoate, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. 3-Methylbutyl octanoate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
