Additional information

Based on the available data from study report, the density of test substance was determined following OECD guideline 109 and adopted from method ASTM 854-02. Method followed was according to pycnometer method. The density of the test substance was determined to be 1.5328 gm/cm3 at 20°C and 975.2 hPa.

In a supporting study from handbook, the density of test chemical was determined to be 1.2977 at 25°C.

Additional study from modelling database indicates the density of test chemical as 1.5±0.1 g/cm3.

From another reliable modelling database, the density of test chemical was estimated to be 1.468±0.06 g/cm3 at 20°C and 101325 Pa.
