Applicant's summary and conclusion

Conclusions:

The vapor pressure of MTDID 47403 is 16 Pa (0.12 mm Hg) at 20 °C as determined by EU Method A.4.

Executive summary:

The vapor pressure of MTDID 47403 was determined by the static method. The vapor pressure of MTDID 47403 at 10 °C intervals from approximately 20 °C to 50 °C was determined in two runs. This data was used to determine the vapor pressure of 16 Pa (0.12 mm Hg) at 20°C for MTDID 47403. The test was done according to EU Method A.4 and was GLP compliant; therefore the result is considered reliable without restriction.
