- Parameter:
- probability of ready biodegradability (QSAR/QSPR)
- Remarks on result:
- readily biodegradable based on QSAR/QSPR prediction
Any other information on results incl. tables
* Results with Danish QSAR Database
Model |
Prediction for Ready Biodegradability |
SciQSAR |
Readily Biodegradable (inside applicability domain) |
Leadscope |
Not Readily Biodegradable (outside applicability domain) |
CASE Ultra |
Readily Biodegradable (inside applicability domain) |
* Results with VEGA 1.1.4
The query substance was predicted as “Possible readily biodegradable ” however with low reliability with Ready Biodegradability model (IRFMN) -v1.0.9. The report mentions that the substance was outside the applicability domain.
Applicant's summary and conclusion
- Interpretation of results:
- readily biodegradable
- Conclusions:
- Based on multiple QSAR models applied, the test item was predicted as readily biodegradable.
