It is described that an LD50 value was 2,046 mg/kg for females and 1,685 mg/kg for males in an acute toxicity test by oral administration to rats, and the primary signs of toxicity were increased respiration, tremors, and slight convulsions followed by central nervous system depression (HSDB (2009)). It was estimated from the LD50 values that the symptoms occurred at doses corresponding to the guidance values for Category 2, and it was classified in Category 2 (central nervous system). |

It was classified in Category 2 from 96-hour LC50 = 1.9 mg/L for fish (Oryzias latipes) (AQUIRE, 2013). |
11 | Hazardous to the aquatic environment (Long-term) | Category 2 |

H411 |
P273
P391 P501 |
Reliable chronic toxicity data were not obtained. It was classified in Category 2 because it is not rapidly degradable (a degradation rate by BOD: 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1982)), and it was classified in Category 2 in acute toxicity. |
12 | Hazardous to the ozone layer | Classification not possible |
