Description of key information
The boiling point of Pyrazole is 188.7 °C at 1013.25 hPa.
Key value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 188.7 °C
Additional information
A literature review and two studies were conducted. In a weight of evidence approach the literature values and the studies were evaluated.
REAXYS (Balbiano, Gazzetta Chimica Italiana) reports the boiling point of Pyrazole to be 186 -188 °C at 1013 hPa. The Kirk-Othmer Encyclopedia of Chemical Technology ereports the bpoiling point of Pyrazole to be 186 °C at ambient pressure. BASF study BR 89.109 reports the boiling point to be 188.71°C at 1013.25 hPa and BASF study BRU 79.75 reports the boiling point to be 187.2 at 1013 hPa.
All values are in the same range and regarded to be reliable for Pyrazole. The value which originates from BASF study BRU 89.109 was chosen as key value
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
