Principle of Boiling point test

The boiling point of a liquid is the temperature at which that liquid is converted to a gaseous state. It can be defined as the temperature at which the vapour pressure of the liquid becomes equal to the pressure at the surface of the liquid.

Conclusions:
The boiling point determination of Isopropyl 4-hydroxybenzoate (CAS No. 4191-73-5) was done following OECD Guideline 103 and according to the method of Siwoloboff and boiling point was determine to be greater than 270 °C at 966.9 hPa.
Executive summary:

The boiling point determination of Isopropyl 4-hydroxybenzoate (CAS No. 4191-73-5) was done following OECD Guideline 103 and according to the method of Siwoloboff and boiling point was determine to be greater than 270 °C at 966.9 hPa

Description of key information

The boiling point determination of Isopropyl 4-hydroxybenzoate (CAS No. 4191-73-5) was done following OECD Guideline 103 and according to the method of Siwoloboff and boiling point was determine to be greater than 270 °C at 966.9 hPa.

Key value for chemical safety assessment

Additional information

The boiling point determination of Isopropyl 4-hydroxybenzoate (CAS No. 4191-73-5) was done following OECD Guideline 103 and according to the method of Siwoloboff and boiling point was determine to be greater than 270 °C at 966.9 hPa.

Based on available data from authoritative database, the boiling point of chemical isopropyl 4-hydroxybenzoate was determined to be in the range of 158 degree C to 160 degree C at 5 torr pressure.

Thus based on the first experimental key study boiling point was consider to be greater than 270 °C at 966.9 hPa.
