Applications

N-Ethylmorpholine is a component of the buffer used in basic peptide separation through anion-exchange chromatography. Further, it acts as a catalyst in the preparation of polyurethane foam.

Notes

Light and air sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with oxidizing agents.

Literature References

Base for use in peptide and similar coupling reactions. For example, has been used in conjunction with ethyl chloroformate for the mild coupling of substituted aromatic acids with primary amines or for the coupling of N-hydroxysuccinimide active esters with peptide residues: J. Med. Chem., 34, 2328 (1991). Compare 4-Methyl­morpholine, A12158. For peptide reagents, see Appendix 6.
