Allyl alcohol (IUPAC name: 2-propenol) is an organic compound with the structural formula CH₂=CHCH₂OH. Like many alcohols, it is a water-soluble, colourless liquid, but it is more toxic than typical small alcohols. Allyl alcohol is used as a raw material for the production of glycerol, but is also used as a precursor to many specialized compounds such as flame-resistant materials, drying oils, and plasticizers. Today allyl alcohol can be obtained by many methods. Allyl alcohol is the smallest representative of the allylic alcohols.
