| GENERAL DESCRIPTION OF PYRROLE | ||
| Pyrrole: One of a class of organic heterocyclic compounds of five-membered diunsaturated ring structure composed of four carbon atoms and one nitrogen atom. The simplest member of the pyrrole family is pyrrole itself, a basic heterocyclic compound; colorless to pale yellow, toxic oil with pungent taste and similar to chloroform odor; insoluble in water; soluble in alcohol, ether, and dilute acids; boils at 129 - 131 C; polymerizes in light. Pyrrole ring system is involved in coloured products (green pigment, chlorophyll; red, hemoglobin; , blue, indigo) in nature. Pyrrolidine, the saturated tetrahydropyrrole, is part of the structures of amino acids (proline, hydroxyproline and hygrine). Pyrroline is a pyrrole in which one of the two solid bonds has been hydrogenated. Pyrrole and its derivatives are widely used as an intermediate in synthesis of pharmaceuticals, medicines, agrochemicals, dyes, photographic chemicals, perfumes and other organic compounds. They are also used as catalysts for polymerization process, corrosion inhibitors, preservatives, and as solvents for resins and terpenes. They are used in metallurgical processes. They are useful in the intensive study of transition-metal complex catalyst chemistry for uniform polymerization, luminescence chemistry and spectrophotometric analysis. | ||
