1,3-Bis(3-(dimethylamino)propyl)urea is an aliphatic organic chemical principally used as a curing agent in epoxy chemistry and a blowing agent in the polyurethane foam industry. It has the formula C₁₁H₂₆N₄O. It is on TSCA and also on EINECS and thus by definition, REACH registered with a number of 257-861-2. ^[1] The CAS number is 52338-87-1. ^[2]

Uses

As the material has tertiary amine functionality, it finds use as a catalyst for polyurethane foam production. ^{[3] [4]} The molecule has two secondary amines and thus can be used to cure epoxy resin based materials. ^[5] Other uses include as a propellant and also blowing agents. The amine functionality allows it to be used as an intermediate to synthesize other compounds. ^{[6] [7]}
