Additional information

Information regarding vapour pressure of IPA was sourced from two separate handbooks. CRC Handbook of Chemistry and Physics (81st Ed) and NIOSH Pocket Guide to Chemical Hazards, which are known to contain peer-reviewed data of Klimisch-2 reliability report that the substance has a vapour pressure of 60.2 hPa at 25 °C (6020 Pa at 298.15 K) and 44 hPa at 20 °C (4400 Pa at 293.15) respectively.
