Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
Endpoint:
biodegradation in water: ready biodegradability
Type of information:
(Q)SAR
Adequacy of study:
other information
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, with adequate and reliable documentation / justification
Justification for type of information:
Documentation about the justification is provided in attachment (See Supporting information). The reliability assessment of the prediction is presented in the attached document as well (QPRF). QSAR model reporting format is presented in the QMRF file attached.
Qualifier:
equivalent or similar to guideline
Guideline:
other: ECHA guidance on information requirements and chemical safety assessment Chapter R.6: QSARs and grouping of chemicals.
Principles of method if other than guideline:
Lombardo A, Pizzo F, Benfenati E, Manganaro A, Ferrari T, Gini G (2014). A new in silico classification model for ready biodegradability, based on molecular fragments. Chemosphere. 108, 10–16 http://dx.doi.org/10.1016/j.chemosphere.2014.02.073
Specific details on test material used for the study:
CC(=O)N1C2=CC=CC=C2CCC3=C1C=C(C=C3)[N+](=O)[O-]

The prediction was deemed to be non reliable on the basis of the parameters listed above. The molecule does not fall into the applicability domain of the model.

Interpretation of results:
not readily biodegradable

Description of key information

The QSAR prediction cannot be considered fully reliable. However, there are some groups that hints the substance is not readily biodegradable. Overall, ready biodegradability can be excluded for the substance.

Key value for chemical safety assessment

Biodegradation in water:
not biodegradable
