Vapour Pressure: 4.12E-09 hPa at 25 °C
Log Kow: 3.4 at 21.5 °C and pH 6.4
Water Solubility: 300 mg/L at 25 °C
Flash point: 227 °C at 1013 hPa

Bisphenol A is a white solid melting at 155 °C and boiling at 360 °C under decomposition. With a moderate water solubility of 300 mg/L and log Kow of 3.4, Bisphenol A is expected to adsorb somewhat to soil and sediment and not migrate through groundwater. With a pKa of 11.3, Bisphenol A is not expected to significantly dissociate in water at environmentally relevant pH values (5 to 8).
