1,2,3,7,8,9-Hexachlorodibenzofuran

Description:
1,2,3,7,8,9-Hexachlorodibenzofuran (CAS 72918-21-9) is a chlorinated aromatic compound belonging to the dibenzofuran family. It is characterized by the presence of six chlorine atoms substituted on the dibenzofuran structure, which consists of two fused benzene rings connected by an oxygen atom. This compound is typically a white to off-white solid and is known for its persistence in the environment, as well as its potential for bioaccumulation in living organisms. Due to its chlorinated nature, it exhibits significant hydrophobicity, leading to low solubility in water but higher solubility in organic solvents. 1,2,3,7,8,9-Hexachlorodibenzofuran is of concern due to its toxicological properties, including potential carcinogenic effects and endocrine disruption. It is classified as a persistent organic pollutant (POP) and is subject to regulatory scrutiny under various environmental protection frameworks. Its production and use have been largely restricted or banned in many countries due to these health and environmental risks.
