Propyl propanoate (also known as propyl propionate and n-propyl propionate) is the organic compound with the molecular formula C6H12O2. It is the ester of propanol and propionic acid. Like most esters, propyl propanoate is a colorless liquid with a fruity odor. The scent of propyl propionate is described as a chemically tinged pineapple or pear. It is used in perfumery and as a solvent.[https://web.archive.org/web/20200630023530/https://www.eastman.com/Products/producthome.asp%3FProduct%3D71065273 Eastman MSDS]{{cite encyclopedia|author=
