General description

Sodium thiomethoxide is mainly used as a reagent in organicsynthesis, especially as a strong nucleophile for various reactions such astransesterification reactions and condensation reactions. It is also asulfur source to prepare various inorganic and organosulfurcompounds.

Application

Sodium thiomethoxide can be used:
  • As a precursor to synthesize sulfonyl-containing dipolar glass polymers.
  • To fabricate semiconductors for organic field effect transistors.
  • To synthesize mono- and dithiols of tetraethylene glycol andpoly(ethylene glycol)s via transesterification reaction.
