Description of key information

OECD Guidelines for testing of chemicals, Guideline no. 112

Due to the low solubility of the test material the pKa-value could not be determined experimentally. NA-11 has one acidic and no basic group. The pKa value for the acidic group is calculated to be 2,1.

Key value for chemical safety assessment

pKa at 20°C:

Additional information

Due to the calculated pKa-value of 2,1 dissociation of the organic Na-salt NA-11 is to be expected under naturally relevant pH conditions.
