Additional information

The density of test item 1-(2,4-dimethylphenylazo)-2-naphthol (CAS No. 3118-97-6) was determined following OECD Guideline 109 and according to the method Adapted from ASTM D854-02 using pyknometer .The mean density of test item was found to be 0.4702 g/cm³ at 20°C and 965.15 hPa.

Other supporting data is based on prediction done using ACD/I-Lab 2.0 and the density is estimated to be 1.14 g/cm3.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of density as 0.4702 g/cm³at 20 °C and 965.15 hPa, thus considered as key study for the chemical safety assessment.
