Additional information
- According to a prediction QSAR using ACD labs V11.02, boiling point of DPTU (1,3-diphenyl-2-thiourea) is about 323.7-373.7°C at 760 mmHg.
- According to the QSAR MPWIN, DPTU (1,3-diphenyl-2-thiourea) was predicted to have a boiling point of about 364.92 °C +/- 5% (i.e. in the range 346-383°C)
- According to SPARC, boiling point of DPTU (1,3-diphenyl -2-thiourea) is about 395.6-408.7 °C at 760 mm Hg.
- According to the study made with OECD 103, the boiling point of DPTU is determined to be higher than 250°C.
