(Redirected from Propyl propionate)

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 propanoate is described as sharp, chemical, pungent, sweet, fruity, pineapple, winey.[2] It is used in perfumery and as a solvent.[3][4] 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,[5] it is considered a safer substitute for toluene.
