The title ester has found some use in perfume compositions and occasionally in flavor compositions. It is rarely offered commercially, but normally manufactured by the interested party for 'private' use. The ester may hydrolyze under certain, not necessarily abnormal, circumstances, and it is not very popular among perfumers for that reason. Its mission in perfumes is mostly that of 'mellowing' and introducing notes simulating well-aged alcoholic perfume solutions. It is often used in conjunction with Ethyl acetoacetate and similar materials for such purpose.
Produced from Propylene glycol and Propionic anhydride.
