WebEXPERIMENTAL Isotopic Compounds-The synthesis of isovaleric acid-4, 4'-CY3,l-Cl4 has been described previously (1). Isovalerate-4, 4'-CY3,3-Cl4 was prepared by mixing isovalerate-4, 4'-Cl3 and isovalerate-3-CY4. The latter compound was obtained from the condensation product of acetone-2-Cl4 and ethyl cyanoacetate. WebDescription. Ethyl isovalerate is the ethyl ester form of isovalerate formed between ethyl alcohol with isovaleric acid. It is a derivative of valeric acid, mainly found in fruits (one of the major component of blueberry). It is a kind of natural food flavoring agent with a fruity type odor and flavor. It is widely used in perfumery and fragrance.
