Tris-(p-tolyl)-fluorenyl-(9)-phosphonium bromide, also known as TFPB, is a phosphonium salt that serves as a versatile reagent in organic synthesis. It is characterized by its unique structure, which includes a fluorenyl core with three p-tolyl (para-tolyl) groups attached to a phosphonium center, and a bromide counterion. TFPB is widely used as a phase-transfer catalyst, facilitating reactions between organic and inorganic compounds by transferring them between aqueous and organic phases. It is particularly effective in promoting various types of reactions, such as oxidation, reduction, and substitution, due to its ability to stabilize reactive intermediates and improve the overall efficiency of the process. The stability and solubility of TFPB in both polar and nonpolar solvents make it a valuable tool in the synthesis of complex organic molecules and materials.

7293-70-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7293-70-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 7293-70:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*0)=111
111 % 10 = 1
So 7293-70-1 is a valid CAS Registry Number.
