Applicant's summary and conclusion

Conclusions:
The isothermal TGA effusion method was applied for the determination of the vapour pressure of CH02241.
The vapour pressure of the test item at 20°C (293K) and 25°C (298K) was ≤ 2.1 × 10^-3 Pa and ≤ 4.1 × 10^-3 Pa at 20°C and 25°C, respectively.
The weight losses of the test item were obtained with a temperature program above the melting temperature of the test item. According to this, the vapour pressure of the test item (which was, according to the method, extrapolated to 20°C and 25°C) could be slightly overestimated.
