Description
Propyl propionate (CAS 106-36-5, EC 203-389-7, FEMA 2958, NSC 72022) is a short-chain ester produced by the esterification of propionic acid with propanol. It carries no assigned E-code and is commercially referenced under the synonyms propyl propanoate and 1-propylpropanoate.
In flavor and fragrance applications, propyl propionate delivers a fruity, rum-like note at low concentrations, functioning as a flavorant in food and beverage formulations. In coatings and printing inks, it acts as a mid-boiling solvent that improves resin dissolution and controls evaporation rate, supporting film formation and print adhesion.
Propyl propionate is available in FCC-grade for food applications and technical grade for industrial use, supplied as a liquid in drums and IBC containers. It is registered under REACH and must be handled in accordance with applicable CLP classification requirements.
