Metabolite Identification
Common NameEthyl tiglate
DescriptionEthyl tiglate, also known as ethyl tiglic acid or fema 2460, belongs to the class of organic compounds known as fatty acid esters. These are carboxylic ester derivatives of a fatty acid. Ethyl tiglate is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
