Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 19 July 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM E 1719-97 “Vapor Pressure Measurement by Ebuilliometry”
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- dynamic method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: ZF-0002-1884-0 Batch ID 2736469 - Key result
- Temp.:
- 20 °C
- Vapour pressure:
- 213 mm Hg
- 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.

- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Qualifier:
- no guideline followed
- GLP compliance:
- no

- Vapour pressure:
- 33 330.5 Pa
- Remarks on result:
- other: temperature not reported
- Remarks:
- (250 mm Hg)
- 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.
