Description of key information

The vapor pressure of PBSF is 125 mm Hg (16.6 kPa) at 20.0 °C

Key value for chemical safety assessment

Additional information

The key study is classified as reliable with restrictions as it is unknown whether is follows an OECD, ISO or ASTM method as well as its compliance with GLP standards. In another study, vapor pressure was determined to be 107 Torr (14.3 kPa) which supports the key study results. It is unknown whether the supporting study follows an OECD, ISO or ASTM method and is not compliant with USEPA GLP standards. The key study is the preferred value due to the supporting study's lesser degree of agreement of experimental data as well as inclusion of literature boiling point data into the vapor pressure regression.
