Description
1,1'-[[3-(Dimethylamino)propyl]imino]bis(propane-2-ol), commonly known as DPA and sold under trade names including Jeffcat DPA, Fentacat 11, Texacat DPA, and PE 4360, is a tertiary amine diol registered under CAS 63469-23-8 and EC 264-261-4. It carries no assigned E-code.
In water treatment and metalworking fluids, DPA functions as a corrosion inhibitor and pH buffer by donating electron pairs to metal surfaces and neutralising acidic species in solution. In coatings and adhesive formulations, its hydroxyl groups enable reactive incorporation into polyurethane systems while the amine nitrogen provides catalytic activity during cure.
DPA is supplied as a neat liquid and is subject to REACH registration requirements for EU import and use. Procurement quantities typically range from drum to IBC scale. Buyers should request a current Safety Data Sheet and confirm supplier REACH compliance documentation before ordering.
