The effects of orally administered benzyl chloride (BCI) on fetal development were evaluated in the rat. Doses of BCI at 0, 50, or 100 mg/kg in corn oil were given daily on 6–15 of gestation. No toxic symptoms were observed following exposure of pregnant rats to BCI. Fetotoxicity in the form of reduced fetal length was observed when dams were treated with BCI at 100 mg/kg. Benzyl chloride did not statistically increase the number of skeletal and visceral variations.
