Description of key information

Dissociation constant was determined to be pKa 9.83 at 25ºC; QPSR online calculator SPARC; Kruetzer (2011b)

Key value for chemical safety assessment

pKa at 20°C:
9.83

Additional information

The pKa of hexenyl-3-cis salicylate was estimated using the validated QPSR online calculator SPARC ( http://archemcalc.com/sparc/). The pKa at 25°C was determined to be 9.83; this suggests that the pKa of the substance is outside the environmentally relevant pH range and that the substances therefore does not dissociate under normal conditions.
