Applicant's summary and conclusion
- Conclusions:
- Using the isothermal thermogravimetric effusion method, the vapour pressure of the substance at 25°C has been determined as 1.3E03 Pa. The vapour pressure of the substance at 20°C has been determined as 7.4E02 Pa. The study was in accordance with EC A.4, OECD 104 and EPA OPPTS 830.7950 guidelines and in compliance with GLP.
