Endpoint summary
Administrative data
Description of key information
The No Observed Adverse Effect Level (NOAEL) in Wistar (Han) rats was established at 100 mg/kg/d.
Key value for chemical safety assessment
Repeated dose toxicity: via oral route - systemic effects
Link to relevant study records
- Endpoint:
- short-term repeated dose toxicity: oral
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- For this endpoint a one-to-one read across was performed to a chemical similar compound of the same chemical class with a comparable phys. chem. profile and similar response in biological assays. The relevant study was performed according to GLP and the methods applied are fully compliant with OECD TG 408. A detailed read across justification is provided in chapter 13 of this dossier.

Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Dose descriptor:
- NOAEL
- 100 mg/kg bw/day
- Study duration:
- subchronic
- Species:
