Administrative data
- Endpoint:
- developmental toxicity
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Reference is considered reliable with restrictions (conduct of study prior to establishment of current test guidelines, but the conduct of the study is otherwise equivalent or similar to OECD 414 (2001)) Restrictions/deviation/deficiencies in comparison to OECD TG 414: - purity of the test substance was not stated - body weight was neither recorded on the first day of dosing nor at least every 3 days during the dosing period. - food consumption was not recorded at three-day intervals and did not coincide with days of body weight determination. Food consumption appeared to be part of the clinical observations conducted daily. - gross pathological examination of the females consisted only of the examination of the urogenital tract. - uteri of non-pregnant females were not further examined (e.g. by ammonium sulfide staining) to confirm the non-pregnant status - gravid uteri including the cervix were not weighed. - whereas commonly approximately one-half of each litter is prepared and examined for skeletal alterations and the remainder for soft tissue alterations, in this study instead one-third of each litter was prepared for soft tissue alterations and two-thirds for skeletal tissue alterations. - data on clinical signs were not provided. - age and individual weight of the animals were not given - no analysis of dose administered - data on number and percent of pre- and post-implantation losses were not given

Details on embryotoxic / teratogenic effects:
The administration of up to 50 mg/kg bw of the test material to pregnant mice for 10 consecutive days had no clearly discernible effect on foetal survival. The number of abnormalities seen in either soft or skeletal tissues of the test groups did not differ from the number occurring spontaneously in the sham-treated controls.

- Conclusions:
- NOAEL (maternal toxicity) > 50 mg/kg bw (nominal concentration)
NOAEL (teratogenicity) > 50 mg/kg bw (nominal concentration)
The administration of up to 50 mg/kg bw of the test material to pregnant mice for 10 consecutive days had no clearly discernible effect on nidation or on maternal or foetal survival. The number of abnormalities seen in either soft or skeletal tissues of the test groups did not differ from the number occurring spontaneously in the sham-treated controls.
