Tris-(dimethylamino)sulfonium chloride, also known as TDMAS, is a quaternary ammonium salt with the chemical formula (CH3)2N-S-N(CH3)2-Cl. It is a colorless, crystalline solid that is soluble in water and polar organic solvents. TDMAS is widely used as a phase-transfer catalyst in organic synthesis, facilitating the transfer of reactants between aqueous and organic phases. It is also employed as a reagent in the preparation of various organic compounds, such as sulfonium ylides, which are crucial intermediates in the synthesis of complex molecules. Additionally, TDMAS has applications in the electroplating industry and as a precursor for the synthesis of other sulfonium salts. Its stability, ease of handling, and high catalytic activity make it a valuable tool in the field of chemistry.
The CAS Registry Mumber 59094-54-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,0,9 and 4 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 59094-54: (7*5)+(6*9)+(5*0)+(4*9)+(3*4)+(2*5)+(1*4)=151 151 % 10 = 1 So 59094-54-1 is a valid CAS Registry Number.
