Hexachlorobenzene
Hexachlorobenzene, identified by CAS 118-74-1, is a stable, white, crystalline chlorinated hydrocarbon. Historically, its primary role was as an agricultural fungicide, specifically for seed treatment to combat diseases like bunt in wheat. It also served as an intermediate in various organic synthesis processes. Due to its persistence and cumulative nature in biological tissues, it poses significant health risks, including carcinogenicity, and has been globally banned under the Stockholm Convention on Persistent Organic Pollutants.
