Description of key information

The density of test item disodium-5-amino-4-hydroxy-3-(phenylazo)naphthalene-2,7-disulphonate (CAS No. 3567-66-6) was determined following OECD guideline 109 and according to themethod recommended in the International Pharmacopoeia, fourth Edition, 2014. The mean pour and tapped  density of the test item was found to be0.4000 g/cm3and 0.4880 g/cm3at 32.8oC and 967.3hPa. For the purpose of chemical safety assessment, the reltive tapped density value of 0.4880 has been considered.
