Additional information

On the basis of available data from study report, the density of test chemical was determined following OECD guideline 109 and according to OECD guideline 109 and according to the method adapted from ASTM D 854-02. The mean density of the test item was determine to be 0.9192 g/cm³at 20°C and 968.5 hPa.

In a supporting study from authoritative database, the density of test chemical was determined to be 0.94 g/cm3 at 75.5°C

Additional study from handbook indicates the density of test chemical as 3.31 g/cm3 at 15°C

Based on prediction done using ACD/I-Lab 2.0,the density of test chemical was estimated to be 1.014 ± 0.06 g/cm3.
