Type of information:
experimental study
Adequacy of study:
key study
Study period:
2009-01-13 - 2009-02-10
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:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Deviations:
yes
Remarks:
The temperature during the determination was not constant to ± 0.5 °C. Temperature range was 19.0 - 20.0 °C. As the test item consists of a solid, the change in density is considered as uncritical.
GLP compliance:
yes (incl. certificate)

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).
