Diethyl malate Usage And Synthesis
Chemical Properties
Diethyl malate has a fruity odor with a pleasant herbaceous undertone. It is an ester of dicarboxylic acid
Occurrence
It exhibits two optically active isomers in addition to the optically inactive form; the most common is the l-isomer; reported present in the cultures of certain fungi (Rhizopus). Reported found in raspberry, cognac, malt whiskey, cider, sherry, white, red, port, sparkling, rose, strawberry and bilberry wines
Uses
Diethyl DL-Malate is used as a reagent in the synthesis of dicarboxylic nitroxyalkylamides and nitroxyalkylimides as anti-ischemic agents.
Definition
ChEBI: Diethyl malate is a malate ester obtained by the formal condensation of the two carboxy groups of malic acid with two molecules of ethanol respectively. It has a role as a metabolite.
Preparation
The l-isomer can be prepared by esterification of the l-isomer of the acid with alcohol in the presence of HCl.
