Data source
Reference
- Reference Type:
- other: QSAR
- Title:
- A rigorous test for SPARC's chemical reactivity models: estimation of more than 4300 ionizable pKa's
- Author:
- Hilal, Said, Karickhoff and Carreira
- Year:

Materials and methods
- Principles of method if other than guideline:
- SPARC has been run based on the reference cited above by entering the SMILES string for 3-methoxybutan-1-ol. Only one ionisable site was identified for this substance so the pKa was calculated based on this site.
- GLP compliance:
- no

Applicant's summary and conclusion
- Conclusions:
- 3-methoxybutan-1-ol is calculated as having a dissociation constant of 15.39.
- Executive summary:
It is not possible to chck whether 3 -methoxybutan-1 -ol falls within the domain of the model as no information is available on the model parameters in SPARC. However, SPARC is considered a reliable model for calculating pKa and is considered suitable for use for this endpoint. 3-methoxybutan-1-ol is calculated as having a dissociation constant of 15.39.
