Lindane is one of eight different hexachlorocyclohexane
(HCH), [58-89-9], C6H6Cl6, isomers and
its Chemical Abstract name is 1α, 2α,3β,4α,5α,6β-
hexachlorocyclohexane 58-89-9 (γ-HCH or γ -BHC, benzene
hexachloride) (80). Commercial products containing
lindane are marketed as either a mixture of isomers
or as the pure γ -BHC isomer. Not unexpectedly, lindane
is a highly stable lipophilic compound and it has
been used extensively worldwide as an insecticide. In
contrast, hexachloropentadiene, [77-47-4], C5Cl6, is an
extremely reactive industrial intermediate used as a chemical
intermediate in the synthesis of a broad range of
cyclodiene-derived pesticides, which include endosulfan,
endrin, heptachlor, and several different organohalogen
flame retardants (81).
