Description and Uses
BHC is a white-to-brownish crystalline solid witha musty, phosgene-like odor. Molecular weight = 290.82;Freezing/Melting point = 65℃. Hazard Identification (basedon NFPA-704 M Rating System): Health 2, Flammability 1,Reactivity 0. BCH consists of eight stereoisomers of which thegamma(~) isomer is most insecticidally active and hence mostimportant. See also“Lindane.”
Not produced commercially in the U.S. and its sale is prohibited by the U.S. EPA.
