Applicant's summary and conclusion
- Conclusions:
- The present QSAR prediction was conducted with the EPISuite TM; MPBPWIN v1.43 software. The software uses three separate methods for vapour pressure prediction. However, the molecular weight is the main dose descriptor. The moelcular weight of L lies within the range of molecular weights obtained from the training sets. Thus, the prediction is considered to be reliable. The predicted vapour pressure of the test item is 0,000838 Pa at 25°C.
