- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- CLP: not classified
DSD: not classified - Executive summary:
A high reliable study according to OECD guideline 420 was performed with 5 female Wistar rats under GLP conditions. The animals were treated with 2000 mg/kg bw of the test substance by gavage in a single dose. Clinical signs like ataxia, hunched posture, lethargy and ptosis were observed. The animals appeared normal for four hours or one day after dosing and no deaths occured. The LD50 was therefore set to be > 2000 mg/kg bw.
