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

Based on the key study from study report,the density of Test item 2,3-dimethylphenol (526-75-0) 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.

Based on available data from authoritative database,the density of chemical 2,3-dimethylphenol was determined to be 0.94 g/cm3 at 75.5 degree C.

Other supporting studies from reliable handbook also indicates that the density of chemical 2,3-dimethylphenol was determined to be 3.31 g/cm3 at 15 degree C.

also supported based on prediction done using ACD/I-Lab 2.0,the density of chemical 2,3-dimethylphenol was estimated to be 1.014 ± 0.06 g/cm3.
