1,3-Propanediol (PDO) CAS NO.504-63-2

1,3-Propanediol (PDO) can be used in PTT fiber production. PTT is short for Polytrimethylene Terephthalate and it's a cutting-edge material in plastic industry.1,3-Propanediol can be formulated into a variety of industrial products including composites, adhesives, laminates, coatings, moldings, aliphatic polyesters, copolyesters. It is also a solvent and used as an antifreeze and in wood paint.

1,3-Propanediol (PDO0 is the simplest member of the class of propane-1,3-diols, consisting of propane in which one hydrogen from each methyl group is substituted by a hydroxy group. A colourless, viscous, water-miscible liquid with a high (210℃) boiling point, it is used in the synthesis of certain polymers and as a solvent and antifreeze. It has a role as a protic solvent and a metabolite.
