Principle of method | The density of test item is determined by using pyknometer. It is the ratio of mass of the unit volume of test item at a stated temperature to mass of the same volume of gas free distilled water at a stated temperature. |

Additional information
The density of test chemical was determined following OECD Guideline 109 and according to the Adapted from ASTM D854-02 using glass pyknometer. The mean density of test chemical was determined to be 2.17 g/cm3 at 20°C and 976.6 hPa.
Other supporting study from authoritative database suggests that the density of test chemical was estimated to be 1±0.06 g/cm3 at 20 degree C.
