Developmental toxicity study of dimethylpiperidone.

The potential maternal and developmental toxicity of dimethylpiperidone (DMPD) was assessed in rats. Groups of 25 mated female Crl:CD (SD)IGS BR rats were exposed by inhalation (whole-body exposures) for approximately six hours per day over days 7-21 of gestation (G); day 1G was the day of copulation plug detection. The exposure levels were 0, 52, 260, or 340 (vapor plus aerosol) mg/m3 DMPD.
