β-Hexachlorocyclohexane (β-HCH) is an organochloride which is one of the isomers of hexachlorocyclohexane (HCH). [1] It is a byproduct of the production of the insecticide lindane (γ-HCH). It is typically constitutes 5–14% of technical-grade lindane, [ 2 ] though it has not been produced or used in the United States since 1985. [ 1 ]
Hexachlorocyclohexane. Hexachlorocyclohexane (HCH), C. 6H. 6Cl. 6, is any of several polyhalogenated organic compounds consisting of a six-carbon ring with one chlorine and one hydrogen attached to each carbon. This structure has nine stereoisomers (eight diastereomers, one of which has two enantiomers), which differ by the stereochemistry of ...
Lindane is the gamma isomer of hexachlorocyclohexane ("γ-HCH"). In addition to the issue of lindane pollution, some concerns are related to the other isomers of HCH, namely alpha-HCH and beta-HCH, which are notably more toxic than lindane, lack its insecticidal properties, and are byproducts of lindane production.

Haloalkane dehalogenases are found in certain bacteria and belong the alpha-beta hydrolase fold superfamily of enzymes. They participate in several metabolic pathways : 1,2-dichloroethane degradation, 1-chloro-n-butane degradation, hexachlorocyclohexane degradation, 1,2-dibromoethane degradation, 2-chloroethyl-vinylether degradation, and 1,3 ...
Hexachlorobenzene is a stable, white, crystalline chlorinated hydrocarbon. [ 7 ] It is sparingly soluble in organic solvents such as benzene, diethyl ether and alcohol, but practically insoluble in water with no reaction. It has a flash point of 468 °F and it is stable under normal temperatures and pressures.
