Application

Methyl sulfate sodium salt can be used to synthesize:
  • Methylsulfate anion based 1,3,4-trialkyl-1,2,3-triazolium ionic liquids for use in Morita–Baylis–Hillman reaction.
  • Anisole by reacting with phenol.
  • Hydroxyanilino quinolines for use as RET kinase inhibitors.

Reactant or reagent involved in:
  • Studying lamellar structure formation in hybrid nanomaterials created by miniemulsion
  • EPR studies of radical ions radiolytically generated from ionic liquids, used as a reference
  • Micellular studies specifically the rate-retarding effects on hydrolysis of substituted 1-benzoyl-1,2,4-triazoles and self-assembly / microstructure of mixed micelles
