The chemical compound propyl acetate, also known as propyl ethanoate, is a common solvent. This clear, colourless liquid is known by its characteristic odour of pears. Due to this fact, it is commonly used as a flavouring additive. It is formed by the esterification of acetic acid and 1-propanol, often via Fischer–Speier esterification.
