Description of key information

The reported vapour pressure of the test substance at 20°C (293K) was 0.000000013 Pa and at 25°C(298K) was 0.000000015 Pa

Key value for chemical safety assessment

Vapour pressure:
0 Pa
at the temperature of:
20 °C

Additional information

The isothermal TGA effusion method was applied for the determination of the vapour pressure of Montelukast Backbone Diol.

The vapour pressure of the test substance at 20°C (293K) was 0.000000013 Pa and at 25°C(298K) was

0.000000015 Pa. For the CSR the vapor pressure result of 0.00000132 Pa which is 3 orders of magnitude higher than tested results, was used as the key value to avoid an "out of range message" and error.
