Description of key information

pka(acidic form) = 2.1

Key value for chemical safety assessment

Additional information

Based on the attached Evans's pKa table and the structure of target substance which is a sodium salt of sulfonic acids, the value for pKa is considered equal to pkA sulfonic acid = 2.1. Therefore the substance in the environmental conditions is considered completely dissociated and no further analysis is required.
