Metabolite Identification
Common NameDiethyl tartrate
DescriptionDiethyl tartrate, also known as fema 2378, belongs to the class of organic compounds known as beta hydroxy acids and derivatives. Beta hydroxy acids and derivatives are compounds containing a carboxylic acid substituted with a hydroxyl group on the C3 carbon atom. Diethyl tartrate is an organic compound, the ethyl ester of tartaric acid. Diethyl tartrate is an extremely weak basic (essentially neutral) compound (based on its pKa). Diethyl tartrate is a mild, earth, and fruity tasting compound. Outside of the human body, Diethyl tartrate has been detected, but not quantified in, alcoholic beverages. This could make diethyl tartrate a potential biomarker for the consumption of these foods. In the Sharpless epoxidation, diethyl tartrate and titanium isopropoxide form a chiral catalyst in situ. It exists in both as a chiral isomer, showing both left- and right-handed forms, as well as a meso stereoisomer, which is not chiral. The chiral isomer is far more common.
