Uses
2,2′-Dipyridyl N-oxide(Obpy) may be used to synthesize the following:2,2′-bipyridyl-6-carbonitrile4-nitro-2,2′-bipyridyl N-oxide by reaction with potassium nitrate in sulfuric acidEu(TTA)3(Obpy), an electroluminescent red emitter obtained via reaction with europium(III) chloride hexahydrate (EuCl3.6H2O) and 2-thenoyltrifluoroacetonate(TTA)
General Description
2,2′-Dipyridyl N-oxide is a mono-N-oxide of 2,2′-bipyridine. It is widely used as a chelating agent. 2,2′-Bipyridine N-oxide readily forms complexes with transition metal perchlorates and divalent 3d metal nitrates. It can be prepared from 2,2′-bipyridyl.
Check Digit Verification of cas no
The CAS Registry Mumber 33421-43-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,4,2 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33421-43:
(7*3)+(6*3)+(5*4)+(4*2)+(3*1)+(2*4)+(1*3)=81
81 % 10 = 1
So 33421-43-1 is a valid CAS Registry Number.

Synthesis and spectral properties of ruthenium(II) complexes based on 2,2′-bipyridines modified by a perylene chromophore
Kodama, Koichi,Kobayashi, Akinori,Hirose, Takuji
supporting information, p. 5514 - 5517 (2013/09/23)
Five new 2,2′-bipyridines functionalized with a perylene or a perylenediimide moiety were synthesized and the corresponding heteroleptic ruthenium(II) complexes ([Ru(bpy)2(L)](PF6)2; bpy = 2,2′-bipyridyl, L = perylene-substituted bpy ligand) were prepared. The UV-vis spectra of the ruthenium(II) complexes showed red-shifted and intense absorption bands derived from the conjugated structure of the new ligands.
