Application

4-Methylmorpholine can be used as:
  • A precursor to prepare N-methylmorpholine N-oxide and 1-butyl-1-methylmorpholinium bromide ([BMmo][Br]), a monocation ionic liquid.
  • A reactant to synthesize quaternary ammonium complexes applicable as complexing agents in redox flow batteries.
  • A basic catalyst in the synthesis of thiobenzamides via Willgerodt-Kindler′s reaction.
  • An activating agent to synthesize hyaluronic acid-based biopolymer for cosmetic, pharmaceutical, and nutraceutical applications.
