Alpha-Hexachlorocyclohexane α-Hexachlorocyclohexane (α-HCH) is an organochloride which is one of the isomers of hexachlorocyclohexane (HCH). 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. Lindane however has not been produced or used in the United States for more than 20 years. At ambient temperatures it is a stable white powdery solid substance.
