应用
Trimethylamine N-oxide dihydrate is used as an oxidizing agent in organic synthesis. It is also used to make quaternary ammonium compounds and a warning agent for flammable gas. Further, it acts as a flavoring agent or adjuvant. It serves as an oxidant for the catalytic osmium tetraoxide cis-hydroxylation of hindered olefins. In addition to this, it is used as a reactant for C-H bond cleavage and decarbonylating agent for solvent-free reactions.

备注
Hygroscopic. Incompatible with acids, acid chlorides, acid anhydrides and oxidizing agents.
