White powder. Soluble in hot water, ethanol; soluble with difficulty in cold water and acetone; not dissociated in benzene and chloroform solutions; distinctly different from the isomeric adduct of trimethylamine oxide and sulfur dioxide.
The Uses of SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX
Separation of isomers, soil sterilant, catalyst for thermosetting resins.
The Uses of SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX
Reactant for sulfation reactions involving:
- Synthesis of sulfate-conjugated resveratrol metabolites
- Chitooligosaccharides used for anti-HIV-1 activity
- Dodecyl thioglycopyranoside used as a surfactant for enantiomeric separation
- Glycosaminoglycans which facilitate activation of signaling pathways dependent on sulfation pattern
- Polysaccharides as heparan sulfate mimetics
Nucleophile for the synthesis of α-tosyloxy ketones
