Ester Definition Esters are the derivatives of carboxylic acids in which the hydrogen of carboxylic acid (-COOH) has been replaced by an alkyl group (-R) like methyl, ethyl or a benzene ring like phenyl. The ester functional group may be represented as -COOR. Esters are found in flowers and fruits which owe their fragrance for these compounds. Esters are commonly used in the preparation of artificial flavors or fragrances. Flavors and fragrances may utilize a single ester or a mixture of esters and other substances to duplicate the odor and flavor of a particular fruit. Some esters that smell like common materials that can be prepared in the laboratory are listed in Table 1.
