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
