As relevant information, the substance was classified as "Sh" in the assessment of MAK/BAT (MAK/BAT (2009)).
5 Germ cell mutagenicity Not classified - - - - The substance was classified as "Not classified" based on the negative results in the micronucleus test using mice intraperitoneally administered (in vivo mutagenicity test in somatic cells) (SIDS (Access on Dec. 2010)). As relevant information, as for in vitro studies, negative results in the Ames test using bacteria and the micronucleus test using Chinese hamster were reported (SIDS (Access on Dec. 2010)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - In the oral administration study in wistar rats (day 6 - 19 postcoitum) (OECD TG414, GLP-compliant), at the high dose level of 90 mg/kg/day, general toxicity (blood system and liver) of the maternal animal was observed. But, no effect on gestational parameters and fetal development were observed (SIDS (Access on Dec. 2010)). In the 3-month oral administration study in male and female wistar rats (OECD TG408, GLP-compliant), the general toxicity (blood system and liver) was seen at 60 mg/kg/day. On the other hand, changes in the weights of reproductive organs were not seen in 120 mg/kg/day (SIDS (Access on Dec. 2010)). However, since there was no data for the development of postnatal offspring, the classification was not possible.
