DiEthyl Malonate (DEM), 99%, 16 oz (500 g) bottle, for organic chemistry use

From Wikipedia: Diethyl malonate, also known as DEM, is the diethyl ester of malonic acid. It occurs naturally in grapes and strawberries as a colorless liquid with an apple-like odor, and is used in perfumes. It is also used to synthesize other compounds such as barbiturates,artificial flavorings, vitamin B1, and vitamin B6. On-line chemists like NileRed and Qwerty Qwerty show videos of interesting uses of this chemical. Several other videos show how you can synthesize this Diethyl Malonate yourself.
