Additional information

Three QSAR software are used for an estimation of the vapour pressure of DPTU :

  • with ACD labs software, vapor pressure of DPTU (1,3-diphenyl-2-thiourea) is about 4.93e-5 torr at 25°C (i.e. 5.57 e-3 Pa)
  • with MPBWIN, VP is on the range : 1.16e-4 till 4.3e-4 Pa
  • According to SPARC, vapour pressure of 1,3-diphenyl-2-thiourea is about 8.4e-7 Pa - in the range 6.8e-4 Pa till 1.1e-3 Pa.

=> VP of DPTU is lower to 1e-3 Pa at 25°C
