- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Justification for type of information:
- Experimental test result performed using standard test guidelines
- Qualifier:
- according to guideline
- Guideline:
- other: as mentioned below
- Principles of method if other than guideline:
- Measurement of capacity of a compound to dissociate into respective ions.

- Dissociating properties:
- yes
- No.:
- #1
- pKa:
- 0.001
- Remarks on result:
- other: not specified
- Conclusions:
- The experimental pKa value for test chemical was determined to be 0.0013 indicating that it has dissociation properties.
- Executive summary:
The experimental pKa value for test chemical was determined to be 0.0013 indicating that it has dissociation properties.
Reference
The low pKa value of 0.0013 indicates that test chemical has a good tendency to dissocite to form ions in water.
Description of key information

Key value for chemical safety assessment
- pKa at 20°C:
- 0.001
Additional information
The experimental pKa value for test chemical was determined to be 0.0013 indicating that it has dissociation properties.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
