Description and Uses

1,3-Propanediol is used as a solvent for thin film preparations, in the production of polymers such as polytrimethylene terephthalate, adhesives, laminates, coatings, moldings, aliphatic polyesters, as an antifreeze and in wood paint. It also acts as a reagent for vinyl epoxide synthon, for epoxide ring-opening, for polymerization reactions and for natural product syntheses.
