Bis(2-dimethylaminoethyl) ether

Bis(2-dimethylaminoethyl) ether (CAS 3033-62-3) is a tertiary diamine ether commercially available under trade names including NIAX A-1, NIAX A-99, Kalpur PC, and A 99. It carries no assigned E-code and is classified under HS code 29221990 within the broader amines category.

In polyurethane foam production, it functions as a blowing catalyst, selectively accelerating the water-isocyanate reaction to control cell structure and rise time. It also serves as a pH buffer and antimicrobial agent in formulated systems, where its dual amine groups allow it to neutralize acidic species and disrupt microbial activity at controlled concentrations.

The compound is supplied as a clear liquid and is available in technical and industrial grades. It falls under REACH registration requirements for EU supply and should be handled in accordance with applicable CLP classification. Packaging is typically offered in drums and intermediate bulk containers.
