Metabolite Identification
Common NameDiethyl malonate
DescriptionDiethyl malonate is found in alcoholic beverages. Diethyl malonate is a flavour ingredient. Diethyl malonate is present in guava fruit, melon, concord grape, pineapple, blackberry and many wines and spirits Malonic acid is a rather simple dicarboxylic acid, with two carboxyl groups close together in its molecule. In forming diethyl malonate from malonic acid, the hydroxyl group (-OH) on both of the carboxyl groups is replaced by an ethoxy group (-OEt; -OCH2CH3). The methylene group (-CH2-) in the middle of the malonic part of the diethyl malonate molecule is neighboured by two carbonyl groups (-C(=O)-)
