Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Link to relevant study record(s)

Reference
Endpoint:
biodegradation in water: screening test, other
Type of information:
(Q)SAR
Adequacy of study:
other information
Study period:
October, 2018
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model, but not (completely) falling into its applicability domain, and documentation / justification is limited
Principles of method if other than guideline:
OPERA V1.5
US EPA Computational Toxicology (CompTox) Chemicals Dashboard
Parameter:
half-life in days (QSAR/QSPR)
Value:
4.65

Model Results

Predicted value: 4.65 days

Global applicability domain: Outside

Local applicability domain index: 0.31

Confidence level: 0.75

See QMRF for details

Interpretation of results:
readily biodegradable
Conclusions:
Biodegradation half-life predicted to be 4.65 days based on experimental values for similar chemicals (outside applicability domain).
