Tris-(m-tolyl)-fluorenyl-(9)-phosphoniumbromid, also known as 2,7-bis(3-methylphenyl)-9-(3-methylphenyl)-9-phosphabicyclo[3.3.1]nonane bromide, is a phosphonium salt with the chemical formula C27H24PBr. It is a white crystalline solid that is soluble in organic solvents. Tris--fluorenyl-(9)-phosphoniumbromid is widely used as a phase-transfer catalyst in various organic reactions, particularly in the synthesis of pharmaceuticals, agrochemicals, and other specialty chemicals. Its unique structure allows for efficient transfer of anions between immiscible liquid phases, facilitating reactions that would otherwise be difficult or impossible to achieve. The bromide counterion in Tris--fluorenyl-(9)-phosphoniumbromid can be replaced with other anions, depending on the specific application requirements.

7293-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7293-71-2 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 1 respectively.Calculate Digit Verification of CAS Registry Number 7293-71:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*1)=112
112 % 10 = 2
So 7293-71-2 is a valid CAS Registry Number.
