Allyl alcohol

Allyl alcohol (CAS 107-18-6) is a short-chain unsaturated alcohol also known as 2-propenol, vinylcarbinol, and 2-propen-1-ol. The reactive double bond adjacent to the hydroxyl group distinguishes it chemically from saturated alcohols and drives its utility as a reactive intermediate rather than a simple solvent.

In polymer production, allyl alcohol serves as a monomer and chain-transfer agent in the synthesis of allyl ester resins and polyols used in coatings and crosslinked plastics. In pharmaceutical manufacturing, it functions as a building block for active ingredient synthesis, where the allylic position enables selective functionalization. Agricultural chemical producers use it as a soil fumigant precursor, where controlled reactivity targets soil-borne pathogens.

Allyl alcohol is supplied in technical and high-purity grades and is subject to REACH registration requirements within the EU. It is classified as a hazardous substance under CLP regulations, which governs packaging, labelling, and transport documentation. Procurement teams should confirm SDS compliance and ADR transport classification prior to ordering.
