4,4'-Bipyridine (abbreviated to 4,4'-bipy or 4,4'-bpy) CAS: 553-26-4 is a bipyridine which is mainly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C5H4NCH3)2]2+, known as paraquat. This species is electroactive, and its toxicity arises from the ability of this dication to interrupt biological electron transfer. Because of its structure, 4,4′-bipyridine can bridge between metal centres to give coordination polymers. 4,4′-Bipyridine can also mediate electronic effects between two paramagnetic metal centers.
4,4'-Bipyridine CAS: 553-26-4 is used in the preparation of nanostructures obtained by self-assembly of Ag6[PV3Mo9O40] with N-donor ligands. 4,4'-Dipyridyl is used in the preparation of coordination polymers.
4,4'-Bipyridine CAS: 553-26-4 was first obtained in 1868 by the Scottish chemist Thomas Anderson (1819–1874) via heating pyridine with sodium metal. However, Anderson's empirical formula for 4,4′-bipyridine was incorrect. The correct empirical formula, and the correct molecular structure, for 4,4′-bipyridine was provided in 1882 by the Austrian chemist Hugo Weidel and his student M. Russo.
