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.
Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and ...
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 ...
1,10-Phenanthroline is an inhibitor of metallopeptidases, with one of the first observed instances reported in carboxypeptidase A. [11] Inhibition of the enzyme occurs by removal and chelation of the metal ion required for catalytic activity, leaving an inactive apoenzyme . 1,10-Phenanthroline targets mainly zinc metallopeptidases, with a much ...
A typical reducing agent is N,N'-bis(trimethylsilyl)-4,4'-bipyridinylidene. Related pyrazine- and cyclohexadiene-based reagents have been developed. They are red or orange THF-soluble solids. The bipyridine reagent is produced by reduction of 4,4'-bipyridine in the presence of trimethylsilyl chloride (Me = CH 3): [2]
The molecular formula C 10 H 8 N 2 (molar mass: 156.18 g/mol, exact mass: 156.0687 u) may refer to: Bipyridines. 2,2'-Bipyridine; 4,4'-Bipyridine

The dicyanobipy can be made by reacting 2,2'-bipy with hydrogen peroxide in acetic acid, (followed by the addition of acetone) to form 2,2'-bipyridine-N,N-dioxide. [1] The 2,2'-bipyridine- N,N -dioxide is then converted into the dicyano compound [ 2 ] by treatment with potassium cyanide and benzoyl chloride in a mixture of water and THF .
