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.[2][3] The refractive index at 20 °C is 1.393.
Because propyl propanoate is a low-odor, moderately volatile ester solvent that is not a hazardous air pollutant (HAP), with good solvent activity and versatility,[4] it is considered a safer substitute for toluene.
