Description of key information

The predicted boiling point of quinine hydrochloride is in the range from 495°C to 632°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
563 °C

Additional information

The predicted boiling point of 631.79 °C is based on the adapted Stein and Brown method, by Epi Suite v4.1. The estimation by calculation of the boiling point given by the ChemSpider database is 495.5°C. The predicted boiling point of quinine dihydrochloride is in the range from 495 - 632°C. We consider the predicted range from 495,5 to 631.79°C to provide an approximation of the boiling point, since experimental measures have not been observed. We consider the predicted value of 631.79°C to provide an approximation of the boiling point, since experimental measures have not been observed. We consider the predicted value of 631.79°C to provide an approximation of the boiling point, since experimental measures have not been observed.

Quinine dihydrochloride might decompose before reaching the boiling point. A study published by Dobbie, 1879 shows that, Quinine decomposed at 256 -257 °C. This might be also applicable to Quinine dihydrochloride
