Applications & Uses
Uses
4-Morpholinopyridine may be used in the synthesis of 1-alkyl-4-morpholinopyridinium halides. It may also be used as a secondary enhancer to improve the chemiluminescence of horseradish peroxidase (HRP) catalyzed oxidation of luminol.
General Description
4-Morpholinopyridine (MORP) can be synthesized by the reduction of its 1-oxide. It undergoes morpholine ring contraction on reacting with trimethylsilylmethyllithium (TMSCH2Li).
