Endpoint summary
Administrative data
Description of key information
In a GLP compliant OECD 422 combined repeated dose toxicity study with the reproductive/developmental screening test in Wistar rats the oral administration of the read-across substance by oral gavage to male and female Wistar rats did not result in signs of systemic toxicity up to a dose level of 1000 mg/kg bw/d.
The no observed adverse effect level (NOAEL) for general systemic toxicity was 1000 mg/kg bw/d for males and females.
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:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Justification for type of information:
- Read-across from the alternative salt form of the substance is justified in section 13.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 422 (Combined Repeated Dose Toxicity Study with the Reproduction / Developmental Toxicity Screening Test)
- Version / remarks:
- 29 July 2016
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: EPA, Health Effects Test Guidelines; OPPTS 870.3650:
- Version / remarks:
- July 2000
- Deviations:
- no
- Specific details on test material used for the study:
- Batch identification: 0013479406
- Species:
- rat
- Strain:
- Wistar
- Remarks:
- strain Crl:WI(Han)
- Sex:
- male/female
- Route of administration:
- oral: gavage
- Dose / conc.:

- Key result
- Dose descriptor:
- NOAEL
- Effect level:
- 1 000 mg/kg bw/day (nominal)
- Based on:
- test mat.
- Sex:
- male/female
- Basis for effect level:
- other: No test substance related adverse effects were observed.
- Key result
- Critical effects observed:
- no
- Conclusions:
- The NOAEL from an OECD 422 combined repeated dose toxicity study with the reproductive/developmental screening test in Wistar rats by oral gavage on the read-across subtance was 1000 mg/kg bw/day. No signs of systemic toxicity were observed up to the highest dose of 1000 mg/kg bw/day. This result is applicable to the registered substance.

Additional information
under the conditions of the OECD 422 combined repeated dose toxicity study with the reproductive/developmental screening test in Wistar rats the oral administration of the read-across substance by oral gavage to male and female Wistar rats did not result in signs of systemic toxicity up to a dose level of 1000 mg/kg bw/d. Thus, the no observed adverse effect level (NOAEL) for general systemic toxicity was 1000 mg/kg bw/d for male and female Wistar rats.
Justification for classification or non-classification
The CLP classification criteria are not met.
