Conclusions:
The vapor pressure of MTDID 22327 is 213 mm Hg at 20 °C.
Executive summary:

A vapor pressure of 213 mm Hg at 20 °C for MTDID 22327 was extrapolated from data measured for the compound using the dynamic method. The vapor pressure and temperature were recorded at a variety of equilibrium points from 27.9 °C to 53.8 °C. The study was conducted following method ASTM E 1719-97 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions.

Conclusions:
A vapor pressure of 33330.5 Pa (250 mm Hg) was reported for MTDID 22327.
Executive summary:

A vapor pressure of 33330.5 Pa (250 mm Hg) was reported for MTDID 22327. Only the result was reported on the SDS and no information about the temperature or method used were provided; therefore the reliability of the data is not assignable.

Key value for chemical safety assessment

Additional information

In the key study, a vapor pressure of 213 mm Hg at 20 °C for MTDID 22327 was extrapolated from data measured for the compound using the dynamic method. The vapor pressure and temperature were recorded at a variety of equilibrium points from 27.9 °C to 53.8 °C. The study was conducted following method ASTM E 1719-97 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions. In a supporting study, a vapor pressure of 33330.5 Pa (250 mm Hg) was reported for MTDID 22327. Only the result was reported on the SDS and no information about the temperature or method used were provided; therefore the reliability of the data is not assignable.
