General description

α-1,2,3,4,5,6-Hexachlorocyclohexane is a racemic compound with anticonvulsant and tremorogenic activities and its accumulation in cerebral white over grey matter in rats was confirmed. Administration of α -1,2,3,4,5,6-hexachlorocyclohexane (α-HCH) to rats decreased the utilization of [2-14C]orotic acid for the synthesis of liver cytidine nucleotides.
