1,3-Benzenediamine, 4-[(4-fluorophenyl)azo]-, also known as 4-(4-Fluorophenylazo)-1,3-benzenediamine, is an organic compound with the chemical formula C12H10FN3. It is a derivative of benzenediamine, featuring an azo group (-N=N-) attached to the 4-position of the benzene ring, and a 4-fluorophenyl group connected to the azo nitrogen. 1,3-Benzenediamine, 4-[(4-fluorophenyl)azo]- is often used as an intermediate in the synthesis of various dyes and pigments, particularly those with yellow to orange hues. Its chemical structure allows for the formation of colored compounds through coupling reactions with diazotized amines, making it a valuable building block in the production of azo dyes.

Check Digit Verification of cas no

The CAS Registry Mumber 75953-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,9,5 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 75953-39:
(7*7)+(6*5)+(5*9)+(4*5)+(3*3)+(2*3)+(1*9)=168
168 % 10 = 8
So 75953-39-8 is a valid CAS Registry Number.

SYNTHESIS OF SOME 2-ARYL-6-AMINO-2,3-DIHYDRO-1,2,4-BENZOTRIAZIN-3-ONES

Slouka, Jan,Bekarek, Vojtech

, p. 1379 - 1387 (2007/10/02)

Acylation of 2,4-diaminoazobenzene and its derivatives Ia-Ih with ethyl chloroformate gives high yields of the corresponding 2,4-bis(ethoxycarbonylamino)azobenzenes IIa-IIh which, on boiling in acid medium, are cyclized with simultaneous splitting off the second ethoxycarbonyl group to give the mesomeric 6-amino-2-aryl-3-oxo-2,3-dihydro-1,2,4-benzotriazinium cations IIIa-IIIh; the latter have been transformed into free bases IVa-IVh or their tautomers Va-Vh.Constitution of the prepared compounds has been studied by IR spectroscopy.Influence of medium on valence vibrations of the carbamate NH groups in the compounds II has also been studied.
