n-Propyl acetate

Propyl acetate, also known as 1-acetoxypropane or propyl ethanoate, belongs to the class of organic compounds known as carboxylic acid esters. These are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). Propyl acetate exists as a clear, colourless liquid with fruity odor and has a bittersweet flavor reminiscent of pear on dilution. It is commonly used in fragrances and as a flavor additive. It can be is synthesized via 1-propanol and acetic acid. It has also been identified in cannabis (PMID: 29783790). Its fruity aroma accounts for the aroma of passion fruit pulps (0.1% - 0.16% relative to total volatile compounds), melons, apples (4.57% - 9.89% relative to total aroma volatiles), and pears (1.31 mg/L in pear juice),
