Phosphorane, tributyl-9H-fluoren-9-ylidene-, also known as 9-(tri-n-butylphosphoranylidene)-9H-fluorene, is a phosphorus-containing organometallic compound with the chemical formula C27H37P. It is a colorless to pale yellow crystalline solid, soluble in common organic solvents such as dichloromethane and tetrahydrofuran. Phosphorane, tributyl-9H-fluoren-9-ylidene- is a phosphorus ylid, which is a type of phosphorus-stabilized carbanion, and it is widely used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Wittig reaction. The structure of this phosphorane consists of a phosphorus atom bonded to three n-butyl groups and a fluorenyl group, which provides the necessary stability for the carbanion center. Due to its reactivity and versatility, it has found applications in the synthesis of various complex organic molecules, including natural products and pharmaceuticals.

7293-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7293-80-3 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, 8 and 0 respectively.Calculate Digit Verification of CAS Registry Number 7293-80:
(6*7)+(5*2)+(4*9)+(3*3)+(2*8)+(1*0)=113
113 % 10 = 3
So 7293-80-3 is a valid CAS Registry Number.
