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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
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.

Solubility
Soluble in water, ethanol, dimethyl sulfoxide and methanol. Sparingly soluble in hot chloroform. Insoluble in diethyl ether, benzene and hydrocarbon solvents.

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