4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is an organic compound with the formula (C 5 H 4 N) 2. It is one of several isomers of bipyridine. It is a colorless solid that is soluble in organic solvents. is mainly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C 5 H 4 NCH 3) 2] 2+, known as paraquat.
Paraquat (trivial name; / ˈ p ær ə k w ɒ t /), or N,N′-dimethyl-4,4′-bipyridinium dichloride (systematic name), also known as methyl viologen, is a toxic organic compound with the chemical formula [(C 6 H 7 N) 2]Cl 2. It is classified as a viologen, a family of redox-active heterocycles of similar structure. [5]
Bipyridines are a family of organic compounds with the formula (C 5 H 4 N) 2, consisting of two pyridyl (C 5 H 4 N) rings. Pyridine is an aromatic nitrogen-containing heterocycle. The bipyridines are all colourless solids, which are soluble in organic solvents and slightly soluble in water. Bipyridines, especially the 4,4' isomer, are mainly of ...
