Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
hydrolysis
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
key study
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Qualifier:
no guideline followed
Principles of method if other than guideline:
The hydrolytic half-life was calculated using SPARC.
GLP compliance:
no
Estimation method (if used):
The acid, neutral and alkanline reaction rates were calculated using SPARC. The half-lives at pH = 4, 7, 10 were then calculated
Transformation products:
no
