Description
N-Ethylmorpholine (CAS 100-74-3) is a tertiary amine supplied under trade names including Dabco NEM, Jeffcat NEM, Toyocat NEM, and Kaolizer 22. It carries no E-code designation and is classified under HS code 29349990. It belongs to the morpholine family of cyclic amines.
In polyurethane foam production, N-ethylmorpholine acts as a blowing and gelling catalyst, accelerating the reaction between isocyanates and water. In pharmaceutical synthesis, it functions as a non-nucleophilic base and reaction solvent, facilitating controlled deprotonation steps. It also serves as a pH buffer and corrosion inhibitor in metalworking fluids.
N-Ethylmorpholine is available in technical and synthesis grades as a liquid, supplied in drums and IBC containers. It is subject to REACH registration requirements within the European Economic Area. Procurement teams should request a current Safety Data Sheet and confirm grade specifications against their application requirements before ordering.
