Hexachlorocyclohexane (HCH) Beta Isomer
Beta-HCH (beta-hexachlorocyclohexane) is a stereoisomer of hexachlorocyclohexane, a chlorinated cyclanic hydrocarbon produced by the chlorination of benzene followed by hydrogenation. It is a persistent byproduct of lindane production and is classified as a halogenated cyclanic derivative. This organochlorine compound is subject to international environmental controls.
