Applicant's summary and conclusion

Conclusions:

The isothermal TGA effusion method was applied for the determination of the vapour pressure of SEZ-250. The vapour pressure of the test substance at 20 Celsius and 25 Celsius was:

20 Celsius
[Pa] [mmHg]) [Pa] mmHg])
2.1 x 10-8 [Pa]
1.6 x 10-10 [mmHg]

25 Celsius
5.5 x10-8 [Pa]
4.1 x 10-10 [mmHg]
