General description

Trimethylamine N-oxide (TMAO) is an amphiphilic osmolyte that can counteract the denaturing effects of urea, pressure, and ice and stabilize the proteins.

Application

Reactant for:
  • C-H bond cleavage
  • Oxidation reactions (oxidant)

  • Decarbonylating agent for solvent-free reactions
Trimethylamine N-oxide dihydrate can react with transition-metal carbonyl cluster compounds and activate CO displacement by converting CO ligands into carbon dioxide.

Other Notes

Oxidant for the catalytic OsO4 cis-hydroxylation of hindered olefins; preparation of the unstable, crystalline anhydrous compound
