Hexachlorobenzene (CAT: R026616) is a fully chlorinated aromatic compound composed of a benzene ring substituted with six chlorine atoms. Originally used as a fungicide and wood preservative, it is now primarily studied for its environmental persistence and toxicological effects. HCB is a persistent organic pollutant (POP) known for its bioaccumulation and long-range atmospheric transport. In scientific research, it serves as a reference compound in studies of chlorinated aromatic degradation, toxicology, and environmental fate modeling. Due to its hazardous nature, handling of hexachlorobenzene is strictly regulated, and its use is limited to controlled laboratory and analytical applications.
