Application

1 3-Propanediol CAS 96-26-4 is white powder. It is mainly used as a building block in the production of polymers such as polytrimethylene terephthalate.
1 3-Propanediol CAS 96-26-4 has a role as a metabolite, an antifungal agent, a human metabolite, a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a mouse metabolite. It is a ketotriose and a primary alpha-hydroxy ketone. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones it acts as a sunscreening agent.
