one of two isomeric alcohols (alcohol) used as solvents and intermediates in chemical manufacturing. The second isomer is isopropyl alcohol (2-propanol).

Normal (n-) propyl alcohol is formed as a by-product of the synthesis of methanol (methyl alcohol) from carbon monoxide and hydrogen. It also occurs in fusel oil. Its largest use is as a solvent in cosmetics (cosmetic) and pharmaceuticals (pharmaceutical industry) and in the preparation of lacquers. It easily forms esters (ester) and ethers (ether), some of which are commercially important.

Propyl alcohol is a colourless, flammable, fragrant liquid that is miscible with water in all proportions and is moderately toxic.
