    PYRIDINE, also called azabenzene and azine, is a heterocyclic aromatic tertiary amine characterized by a six-membered ring structure composed of five carbon atoms and a nitrogen which replace one carbon-hydrogen unit in the benzene ring (C5H5N). The simplest member of the pyridine family is pyridine itself. It is colorless, flammable, toxic liquid with a unpleasant odor, miscible with water and with most organic solvents, boils at 115 InChI=1/C25H36O3/c1-3-4-5-6-7-24. Its aqueous solution is slightly alkaline. Its conjugate acid is called pyridinium cation, C5H5NH+, used as a oxidation agent for organic synthesis.. Pyridine is a base with chemical properties similar to tertiary amines. Nitrogen in the ring system has an equatorial lone pair of electrons, that does not participate in the aromatic pi-bond. Its aqueous solution is slightly alkaline. It is incompatible and reactive with strong oxidizers and strong acids, and reacts violently with chlorosulfonic acid, maleic anhydride, oleum, perchromates, b-propiolactone, formamide, chromium trioxide, and sulfuric acid. Liquid pyridine easily evaporates into the air. If it is released to the air, it may take several months to years until it breaks down into other compounds. Usually, pyridine is derived from coal tar or synthesized from other chemicals, mainly acetaldehyde and ammonia. Pyridine compounds are found in nature. For example, nicotine from tobacco, ricinine from castor bean, pyridoxine or vitamin B and P products, alkaloids (such as coniine, piperine and nicotine), and etc. Some pyridine compounds consumed largely are;

    Picoline : Three structural isomers of methyl pyridines (alpha, бета, gamma- positions)

    Lutidine : Six structural isomers of dimethyl pyridines (2,3-, ,24-, 2,5-, 2,6-, 3,4-, 3,5- positions)

    Collidine : Three structural isomers of trimethyl pyridines (2,3,5-, 2,3,6-, 2,4,6- positions)

    Pyrimidine: Pyridine alteration containing nitrogen atoms at positions 1 а также 3

    Piperidine: Hexahydropyridine (saturated form)

    Nicotinic acid: pyridine-3-carboxylic acid

    Pyrimidine and its derivatives are biologically important components of nucleic acids (DNA, RNA) and coenzymes. Some pyridine system is active in the metabolism in the body. Certain nitrogenous plant products also have pyridine class compounds. They can be the parent compound of many drugs, including the barbiturates. Pyridine and its derivatives are used as solvents and starting material for the synthesis of target compounds such as insecticides, herbicides, medicines, vitamins, food flavorings, feed additives, dyes, rubber chemicals, explosives, disinfectants, and adhesives. Pyridine is also used as a denaturant for antifreeze mixtures, as a dyeing assistant in textiles and in fungicides. 2,3-Dichloropyridine is an intermediate for the synthesis further pyridine derivatives especially for agrochemical field.
