Conclusions:

The density of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 109 using the pycnometer method. The density of the test item was calculated as 1.1272 g/cm3 at 20 ± 1.0°C, which is the mean of two values. Precision of the value is given as maximal error of determination (0.0002 g/cm3).

Executive summary:

The density of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 109 using the pycnometer method.

The density of the test item was calculated as 1.1272 g/cm³at 20 ± 1.0°C, which is the mean of two values. Precision of the value is given as maximal error of determination (0.0002 g/cm³).
