Phenyl-p-tolyl-2,5-dimethyl-phenyl-sulfoniumiodid, also known as 2,5-dimethyl-4-(p-tolyl)phenyl diphenyl sulfonium iodide, is a complex organic compound with the chemical formula C25H24IS. It is a type of sulfonium salt, which is characterized by the presence of a positively charged sulfur atom bonded to three organic groups and a counter ion, in this case, iodide. Phenyl-p-tolyl-2,5-dimethyl-phenyl-sulfoniumiodid is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the generation of carbocations. Its structure features a central phenyl ring with two methyl groups at the 2 and 5 positions, a p-tolyl group (a phenyl ring with a methyl group at the para position) attached to one of the phenyl rings, and a diphenyl sulfonium group. The iodide ion acts as a counter ion, balancing the positive charge on the sulfonium center. Phenyl-p-tolyl-2,5-dimethyl-phenyl-sulfoniumiodid is of interest in the field of synthetic chemistry due to its potential applications in the creation of new molecules and materials.
The CAS Registry Mumber 4024-12-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 4 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4024-12: (6*4)+(5*0)+(4*2)+(3*4)+(2*1)+(1*2)=48 48 % 10 = 8 So 4024-12-8 is a valid CAS Registry Number.
