| Description | Methyl hexanoate, also known as methyl caproate or methyl hexoic acid, belongs to the class of organic compounds known as fatty acid methyl esters. Fatty acid methyl esters are compounds containing a fatty acid that is esterified with a methyl group. They have the general structure RC(=O)OR', where R=fatty aliphatic tail or organyl group and R'=methyl group. Methyl hexanoate is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. |
