4-(Fluorenyl-9-yl)-diphenylmethan, also known as 4-(9H-fluoren-9-yl)-1,1-diphenylmethan, is an organic compound with the molecular formula C27H22. It is a derivative of diphenylmethane, featuring a fluorenyl group attached to the 4-position of the diphenylmethane backbone. 4-(Fluorenyl-(9))-diphenylmethan is characterized by its rigid, planar structure due to the presence of the fluorenyl ring, which is a fused-ring system consisting of a phenyl ring and a cyclohexadienyl ring. The fluorenyl group imparts unique electronic and steric properties to the molecule, making it a valuable building block in the synthesis of various organic compounds, particularly in the field of materials science and pharmaceuticals. Its applications may include the creation of complex molecular architectures, the development of new drugs, or the synthesis of advanced materials with specific optical or electronic properties.
The CAS Registry Mumber 2116-37-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 6 respectively; the second part has 2 digits, 3 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2116-37: (6*2)+(5*1)+(4*1)+(3*6)+(2*3)+(1*7)=52 52 % 10 = 2 So 2116-37-2 is a valid CAS Registry Number.
