Description of key information
Key value for chemical safety assessment
- pKa at 20°C:
- 13.27
Additional information
In the Klimisch 2 non-GLP study from Gries (2012) the pKa-values of Chloroacetamide were calculated using the online software tool SPARC(v4.6 (October 2011 release w4.6.1691 -s4.6.1687)). In the Guidance on information requirements Chapter R.7a: Endpoint specific guidance (May 2008) section R.7.1.17.3 Evaluation of available information on dissociation constant, page 176 it is stated that " ... it is recommended that SPARC be used". Since an international accepted QSAR tool was used this study was considered to be a Klimisch 2 study. The calculations were performed for 20°C.
The calculated pKa values were all far out of the environmentally relevant range, i.e., -4.56, -2.43 and 13.27. Therefore, these QSAR data are considered as acceptable for the further assessment of the test substance without further testing.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
