DiEthyl Malonate (DEM), 99%, 16 oz (500 g) bottle, for organic chemistry use
11 de agosto de 20260
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. But why synthesize so expensively if you can buy it so inexpensively here? You are paying wholesale price for retail quantity. We sell quality products at fraction of our competitors's prices.
