General description

Morpholine can be obtained, via degradation of N-methylmorpholine N-oxide (NMMO) during fiber production.

Morpholine is a cyclic amine that serves as a solvent, corrosion inhibitor, and chemical intermediate.

Application

Morpholine can be used as a buffer component in the separation of peptides and pathogenic lipopolysaccharides during on-line chromatographic preconcentration coupled to capillary zone electrophoresis–electrospray mass spectrometry (cPC–CZE–ES-MS) analysis from colony isolates.
