Administrative data
Link to relevant study record(s)
- Endpoint:
- vapour pressure
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-01-13 - 2009-03-26
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: The GLP study was conducted according to an internationally accepted guideline. All study parameters are based on the specific guideline.
- Qualifier:

- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- effusion method: by loss of weight or by trapping vaporisate
- Temp.:
- 20 °C
- Vapour pressure:
- 0.004 Pa
- Temp.:
- 25 °C
- Vapour pressure:
- 0.006 Pa
- Transition / decomposition:
- no
- Conclusions:
- The vapour pressure of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD Guideline 104 (Vapour Pressure Curve). The following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 0.00356 Pa
Vapour pressure at 25 °C: 0.00624 Pa - Executive summary:
The vapour pressure of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD Guideline 104 (Vapour Pressure Curve). The following vapour pressures at 20 °C and at 25 °C were calculated from the regression equation:
Vapour pressure at 20 °C: 0.00356 Pa
Vapour pressure at 25 °C: 0.00624 Pa
