(E)-Bis-(4-fluoro-phenyl)-diazene dioxide, also known as 1,2-bis(4-fluorophenyl)diazene-1,2-dioxide, is an organic compound with the chemical formula C12H8F2N2O2. It is a derivative of diazenes, which are characterized by the presence of a diazenyl group (-N=N-). This particular compound features two 4-fluorophenyl groups attached to the diazenyl group, with an oxygen atom connected to each nitrogen atom, forming a dioxide structure. It is a colorless solid and is used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its potential reactivity and the presence of the electron-withdrawing fluorine atoms on the phenyl rings. The compound's properties, such as its stability and reactivity, can be influenced by the electron-withdrawing effect of the fluorine atoms, which can alter the molecule's electronic structure and influence its chemical behavior.

728-83-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 728-83-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.Calculate Digit Verification of CAS Registry Number 728-83:
(5*7)+(4*2)+(3*8)+(2*8)+(1*3)=86
86 % 10 = 6
So 728-83-6 is a valid CAS Registry Number.
