Additional information

Information concerning melting/freezing point of IPA was sourced from two separate handbooks. Merck Index: An Encyclopedia of Chemicals, Drugs, and Biologicals (14th Edition) and CRC Handbook of Chemistry and Physics (81st Ed), which are known to contain peer-reviewed data of Klimisch-2 reliability state that the substance has a melting point of -88.5 °C (corresponding to 184.65 K), and -89.5 °C (corresponding to 183.65 K), respectively.
