Triphenyl-(1-trimethylsilanyl-pent-3-ynyl)-phosphonium bromide is a complex organic compound with the chemical formula C27H30BrPSi. It is a phosphonium salt, characterized by the presence of a phosphonium cation (P+) and a bromide anion (Br-). The phosphonium cation consists of a central phosphorus atom bonded to three phenyl groups and a 1-trimethylsilanyl-pent-3-ynyl group. The 1-trimethylsilanyl-pent-3-ynyl group features a trimethylsilyl (SiMe3) moiety attached to a pent-3-ynyl chain, which contains a triple bond. Triphenyl-(1-trimethylsilanyl-pent-3-ynyl)-phosphonium; bromide is often used in organic synthesis as a reagent or catalyst, particularly in reactions involving the formation of carbon-carbon or carbon-heteroatom bonds. Its unique structure, with the trimethylsilanyl group and the triple bond, makes it a versatile building block for the synthesis of various organic molecules.

98291-78-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98291-78-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,9 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 98291-78:
(7*9)+(6*8)+(5*2)+(4*9)+(3*1)+(2*7)+(1*8)=182
182 % 10 = 2
So 98291-78-2 is a valid CAS Registry Number.
