Description of key information

pka is predicted to <1 for the 4-C10-13 sec alkylbenzenesulfonate by  SPARC prediction program. The amine part of the salt is a quaternary amine, no dissociation constant is applicable, the amine is cationic at all pH values.

Key value for chemical safety assessment

Additional information

The substance is a salt of a quaternary amine and 4-C10-13 sec alkylbenzenesulfonate.Therefore the pKa value has been predicted for the sulfonic acid part only.
