Tris-(m-sulfonatophenyl)phosphine is a phosphine-based ligand with the chemical formula C18H15O9PS3. It is a tris(phenyl)phosphine derivative, where each phenyl group is substituted with a m-sulfonato group, resulting in three negatively charged sulfonate groups. tris-(m-sulfonatophenyl)phosphine is widely used in coordination chemistry, particularly in the synthesis of metal complexes, due to its ability to act as a chelating ligand. Its unique structure allows for strong binding to metal ions, making it a valuable tool in various applications, such as catalysis, materials science, and medicinal chemistry. The presence of sulfonate groups also enhances the solubility of the ligand in aqueous solutions, which is beneficial for many chemical reactions and processes.

Check Digit Verification of cas no

The CAS Registry Mumber 91171-35-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 1 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91171-35:
(7*9)+(6*1)+(5*1)+(4*7)+(3*1)+(2*3)+(1*5)=116
116 % 10 = 6
So 91171-35-6 is a valid CAS Registry Number.

PHOSPHINES SULFONEES ASYMETRIQUES V. CINETIQUE DE SULFONATION DES PHOSPHINES

Lecomte, L.,Sinou, D.

, p. 239 - 251 (2007/10/02)

The sulfonation of 1,2-, 1,3- and 1,4-diphosphines (dppe, dppp, dppb) is studied.It is shown that the sulfonation is faster for 1,4-diphophines than for 1,3- and 1,2-diphosphines.The conditions affording the tetrasulfonation are described, and also those allowing the obtention of a mixture containing large amounts of disulfonated diphosphines.This study is extended to chiral diphosphines (Cyclobutanediop, BDPP, Chiraphos).
