Description
SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX is a white powder that is soluble in hot water and ethanol, with difficulty in cold water and acetone. It does not dissociate in benzene and chloroform solutions and is distinctly different from the isomeric adduct of trimethylamine oxide and sulfur dioxide.
Uses
Used in Chemical Synthesis:
SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX is used as a reactant for sulfation reactions for various applications, including the 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, and as a nucleophile for the synthesis of α-tosyloxy ketones.
Used in Pharmaceutical Industry:
SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX is used as a separation agent for isomers, which is crucial in the development and production of various pharmaceutical compounds.
Used in Agriculture:
SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX is used as a soil sterilant, helping to control pests and diseases in agricultural settings.
Used in Manufacturing Industry:
SULFUR TRIOXIDE TRIMETHYLAMINE COMPLEX is used as a catalyst for thermosetting resins, playing a vital role in the production of various industrial materials and products.
Check Digit Verification of cas no
The CAS Registry Mumber 3162-58-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,6 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3162-58:
(6*3)+(5*1)+(4*6)+(3*2)+(2*5)+(1*8)=71
71 % 10 = 1
So 3162-58-1 is a valid CAS Registry Number.

The title compound (MeSO2)2N-SO2-O-SiMe3 (2; m.p. 57 deg C) is obtained by treating (MeSO2)2N-SiMe3 (3) with one equivalent of sulfur trioxide in CH2Cl2 at -20 deg C.The crystal structure of 2 (triclinic, space group P) was established by low-temperature X-ray diffraction.The most interesting feature of the molecular structure is the geometry of the S-O-Si sequence, displaying a very long Si(sp3)-O bond, a short S(sp3)-O bond and a large angle at oxygen (mean values for two independent molecules: Si-O 174.1, S-O 151.1 pm, S-O-Si 134.3 deg).The coordination at nitrogen is trigonal-planar (S-N-S 118.5-121.0 deg, S-N 170.5-173.1 pm). 2 is instantaneously hydrolyzed by excess water to form (MeSO2)2NH, sulfuric acid and (Me3Si)2O.In vacuo at 60 deg C, molten 2 will readily dissociate into its precursors 3 and SO3.It is shown that 2 may react either as an SO3 donor or as a sulfosilylating reagent.Reaction with Lewis bases such as Me3N, pyridine or R2PCl (R = tBu, Ph) proceeds with the formation of the corresponding complexes B*SO3; thermolysis of the isolable phosphane complexes affords the respective phosphane oxides R2(Cl)PO.Sulfosilylation of phenol, cyclohexene or 2,3-dimethyl-2-butene with 2 in CH2Cl2 gives the trimethylsilyl esters of 4-hydroxybenzenesulfonic, cyclohexene-3-sulfonic, or 2,3-dimethyl-1-butene-3-sulfonic acids, respectively.Key words: Trimethylsilyl N,N-dimesylamidosulfonate, synthesis, X-ray structure, long Si(sp3)-O bond, SO3 transfer, sulfosilylation.
