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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Dissociation constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- dissociation constant
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Justification for type of information:
- 1. SOFTWARE
ARChem SPARC. version 4.6
2. MODEL
pKa
3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
See “Test material information”
4. SCIENTIFIC VALIDITY OF THE (Q)SAR MODEL
Information on the OECD criteria as outlined by the applicant is provided below under "Any other information of materials and methods incl. tables".
5. APPLICABILITY DOMAIN
See information provided in "Any other information of materials and methods incl. tables".
6. ADEQUACY OF THE RESULT
See assessment of adequacy as outlined in the "Overall remarks, attachments" section. - Qualifier:
- according to guideline
- Guideline:
- other: REACH Guidance on QSARs R.6
- Principles of method if other than guideline:
- - Software tool(s) used including version: SPARC v4.6
- Model(s) used: pKa
SPARC breaks the molecule into two type of functional units: the reaction center (with known chemical properties) and the perturber. pKa of the reaction center is adjusted for the molecule in question using the mechanistic perturbation models. For the complete method's description see field 'Any other information on materials and methods incl. tables'.
The datasets used for the model development and for the external validation are described in the field 'Any other information on materials and methods incl. tables'.
- Model description: see field 'Any other information on materials and methods incl. tables'.
- Justification of QSAR prediction: see field 'Justification for type of information' and 'overall remarks'. - GLP compliance:
- no
- Dissociating properties:
- no
Reference
No dissociation could be determined within the range pH = -0.2 - 14. For detailed description on the model and its applicability, see "Any other information on materials and methods incl. tables".
Description of key information
no dissociation
Key value for chemical safety assessment
Additional information
The dissociation constant of the substance glycerol tri(2-ethylhexanoate) (CAS 7360-38-5) was determined by QSAR calculation with SPARC (v4.6). No dissociation could be determined within the range pH = -0.2 - 14.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
