Oral administration to rabbits on day 6 to 18 of gestation caused fetal malformations and maternal toxicity at 0.24 g/kg and 5 of malformed fetuses without maternal toxicity at 0.05 g/kg. (HSDB (2011)). Furthermore, resorption of all fetuses in the intraperitoneal administration to pregnant rats (HSDB (2011)) and teratogenicity in the subcutaneous administration to pregnant rats (Teratogenic (12th, 2007), corresponding to List 2) were reported respectively. From the above, it was classified in Category 2 due to all from List 2 data. Besides, it is classified in Repr. Cat. 2; R61 in EU classification (EC-JRC (ESIS) (Access on Nov. 2011)). |

9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | No data. |
10 | Aspiration hazard | Classification not possible | - | - | - | No data. |
