Applications
Sulfur trioxide-trimethylamine complex acts as a reagent for sulfonation and sulfamation reactions. It is used as a reactant for the synthesis of sulfate-conjugated resveratrol metabolites and chitooligosaccharides. It is used in association with dodecyl thioglycopyranoside, which acts as a surfactant for enantiomeric separation. Further, it acts as a nucleophile used for the preparation of alfa-tosyloxy ketones.

Solubility
Soluble in hot water and ethanol. Slightly soluble in dimethyl sulfoxide and methanol. Insoluble in water.

Notes
Moisture sensitive. Incompatible with strong oxidizing agents.
