Esters Many naturally occurring esters are responsible for the pleasant, characteristic smells of various fruits. As a result, synthetic esters are commonly made for use in perfumes and artificial flavours. To produce a synthetic ester with a specific smell, chemists research what ester will give them the specific smell they are interested in and then they work "backwards" to design a chemical reaction pathway to produce the desired ester using commonly available chemicals. Esters are commonly produced by reacting a carboxylic acid with an alcohol, if the required carboxylic acid and alcohol are not commonly available, chemists have to use a multi-step chemical reaction pathway to first produce the carboxylic acid and/or alcohol, and then produce the desired ester. 1.
