Chemical Properties

Diethyl tartrate has a mild, fruity, wine aroma.

Occurrence

The d-isomer has not been reported found in nature; the l-isomer and the racemic form are of little importance. Reported found in sherry, white and red wine.

Uses

Natural Diethyl laevo-tartrate is used as a chiral reagent in a host of chemical reactions, such as the synthesis of isoquinoline alkaloids and arundic acid, which has been used in acute ischemic stroke thera py.
