Results and discussion
Effect levels
- Dose descriptor:
- LD50
- Effect level:
- ca. 2 200.11 mg/kg bw
Any other information on results incl. tables
Model assessment:
Prediction is "LD50 = 2200.11 mg/kg", but the result may be not reliable as only moderately similar compounds with known experimental value in the training set have been found.
Details are provided in attachment on the section: "attached full study report".

- Interpretation of results:
- not classified
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- The obtained results are disregarded as the substance is out from the applicability domain of the model.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
