Description
N,N,N',N'',N''-Pentamethyldiethylenetriamine (CAS 3030-47-5) is a tertiary triamine supplied under trade names including LUPRAGEN N 301 and abbreviated as PMDTA or PMDT. It carries no assigned E-code. The compound is registered under REACH and classified within the broader aliphatic polyamine family.
In polyurethane foam production, PMDTA functions as a tertiary amine catalyst, accelerating the urethane gel reaction by activating isocyanate-polyol coupling. It is also applied in water treatment formulations as a pH buffer and in coatings systems where controlled amine reactivity influences cure rate and film formation.
PMDTA is available as a liquid-phase product supplied in standard drum and IBC formats for industrial procurement. The substance is registered under REACH (EC 221-201-1), and buyers should confirm grade specifications against application requirements, particularly where food-contact or biocidal end-uses apply.
