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.
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.

The molecular and physiological basis of the touch-unresponsive zebrafish mutant fakir has remained elusive. Here we report that the fakir phenotype is caused by a missense mutation in the gene encoding voltage-gated calcium channel 2.1b (CACNA1Ab). Injection of RNA encoding
