Sulfur trioxide-trimethylamine complex, 95%

Description

CAS: 3162-58-1 | C3H9NO3S | 139.17 g/mol

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.

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.
