Conclusions:
The density of test chemical was determined following OECD guideline 109 and according to the method recommended in the International Pharmacopoeia, fourth Edition, 2014. The mean pour density and tapped density of the test chemical was determined to be 0.6250 g/cm³ and 0.7308 g/cm³ at 30.1°C and 975.5 hPa.
Executive summary:

The density of test chemical was determined following OECD guideline 109 and according to the method recommended in the International Pharmacopoeia, fourth Edition, 2014. The mean pour density and tapped density of the test chemical was determined to be 0.6250 g/cm³ and 0.7308 g/cm³ at 30.1°C and 975.5 hPa.
