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 item 1,4-Dichloro-2-nitrobenzene (CAS No. 89-61-2 ) was determined following OECD guideline 109 and according to the method adapted from ASTM D 854-02. The mean density of the test item was observed to be 1.2616 g/cm³ at 20°C and 970.55 hPa.

Study was conducted to determine the density of test chemical 1,4-dichloro-2-nitrobenzene. The density of chemical 1,4-dichloro-2-nitrobenzene is observed to be 1.6 g/cm3 at 20 deg C.

Thus based on the above both studies from experimental study report and other database the mean density of the test item was observed to be in the range of 1.2616 to 1.6 g/cm³.
