Ethyl methylphenylglycidate, commonly known as strawberry aldehyde, is an organic compound used in the flavor industry in artificial fruit flavors, in particular strawberry.[2]

Uses

Because of its pleasant taste and aroma, ethyl methylphenylglycidate finds use in the fragrance industry, in artificial flavors, and in cosmetics.[1] Its end applications include perfumes, soaps, beauty care products, detergents, pharmaceuticals, baked goods, candies, ice cream, and others.

Chemistry

Ethyl methylphenylglycidate contains ester and epoxide functional groups, despite its common name, lacks presence of an aldehyde. It is a colourless liquid that is insoluble in water.

Ethyl methylphenylglycidate is usually prepared by the condensation of acetophenone and the ethyl ester of monochloroacetic acid in the presence of a base, in a reaction known as the Darzens condensation.

Safety

Long-term, high-dose studies in rats have demonstrated that ethyl methylphenylglycidate has no significant adverse health effects and is not carcinogenic.[3] The US Food and Drug Administration has classified ethyl methylphenylglycidate as generally recognized as safe (GRAS).[4]
