Short summary
Organosulfates have been identified in atmospheric secondary organic aerosol (SOA). The thermodynamic properties of SOA constituents, such as organosulfates, affect the stability and atmospheric impact of the SOA. Here we present estimated solubility, activity, pKa, saturation vapor pressure and Henry's law solubility values for several atmospherically relevant monoterpene- and isoprene-derived organosulfate compounds. These properties can be used, for example, in aerosol process modeling.
