Additional information

A number of consistent value are reported for the vapour pressure across a variety of secondary sources indicating a vapour pressure of around 9.7 - 10.3kPa at around 20C. Because of the impact on exposure assessment (the cut off between medium and high fugacity bands as used in ECETOC TRA exposure prediction tool) a conservative choice of 10.3kPa is selected as the key parameter for this end point.
