Diethylamine

Diethylamine (CAS 109-89-7, EC 203-716-3) is a secondary aliphatic amine commonly abbreviated as Et2NH or (C2H5)2NH, also known by the German name Diaethylamin. It carries no assigned E-code and is not classified as a direct food additive, though it functions as a processing aid and flavorant precursor in regulated food applications.

In pharmaceutical manufacturing, diethylamine acts as a pH-adjusting buffer in API synthesis and chromatography mobile phases, where its basicity controls ionization states of target compounds. In polymer production, it serves as a crosslinking catalyst for epoxy and polyurethane systems, accelerating cure by activating reactive functional groups. Personal care formulators use it as an antimicrobial agent and skin-conditioning component in emulsified systems.

Diethylamine is supplied in technical and pharmaceutical grades, with select batches meeting FCC or Ph.Eur. specifications. The substance is registered under REACH and subject to CLP classification requirements. Packaging is available in drums and IBC containers, with documentation including SDS and certificate of analysis as standard.
