In 1867, Henry Bassett proved that the compound produced from benzene and antimony was the same as Julian's carbon chloride and named it "hexachlorobenzene". [ 10 ] [ 9 ] Leopold Gmelin named it "dichloride of carbon" and claimed that the carbon was derived from cast iron and the chlorine was from crude saltpetre .
Lindane, also known as gamma-hexachlorocyclohexane (γ-HCH), gammaxene, Gammallin and benzene hexachloride (BHC), [3] is an organochlorine chemical and an isomer of hexachlorocyclohexane that has been used both as an agricultural insecticide and as a pharmaceutical treatment for lice and scabies.
It is sometimes erroneously called "benzene hexachloride" (BHC). They have been used as models for analyzing the effects of different geometric positions of the large atoms with dipolar bonds on the stability of the cyclohexane conformation. [1] The isomers are poisonous, pesticidal, and persistent organic pollutants, to varying degrees.
While lead-based paint has been banned by the federal government since 1978, according to the EPA, "87% of homes built before 1940 have some lead-based paint, while 24% of homes built between 1960 ...
Although banned as a pesticide more than 30 years ago, traces of beta-HCH can still be found in water and soil. Animal studies show that organochlorine pesticides, including beta-HCH, are neurotoxic , cause oxidative stress , and damage the brain's dopaminergic system .

Stanley Jerome Cristol (June 14, 1916 – January 23, 2008) was an American organic chemist. [2] A chemistry professor and long-time faculty member of the University of Colorado Boulder Chemistry and Biochemistry Department, [1] he was named Chair of the American Chemical Society Colorado Section in 1952, [3] was a two-time Guggenheim Fellowship awardee in 1955 [4] and 1980, [5] and was ...
α-Hexachlorocyclohexane (α-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) and it is typically still contained in commercial grade lindane used as insecticide.
