Applicant's summary and conclusion

Conclusions:
The calculated vapor pressure amounts to 0.000276 mmHg at 25°C, 0.0368 Pa at 25°C respectively.
Executive summary:

The vapor pressure was determined by calculation using EPI Suite 4.0. Calculated boiling point by EPI Suite 4.0 was used for calculation of the vapor pressure.
