DefinitionA <PYRENE COMPOUND> is a <POLYCYCLIC AROMATIC HYDROCARBONS COMPOUND> consisting mainly of pyrene (C16H10), a polycyclic aromatic hydrocarbon (PAH) consisting of four fused benzene rings, resulting in a large, flat aromatic system
Pyrene is the smallest peri-fused polycyclic aromatic hydrocarbon - one where the rings are fused through more than one face. It forms during incomplete combustion of organic material and therefore can be isolated from coal tar along with a broad range of related compounds. Class name according to the IUPAC naming convention.
