Description of key information

The mean density of test itemTrisodium 3-hydroxy-4-(4'-sulphonatonaphthylazo) naphthalene-2,7-disulphonate(CAS No.915-67-3)was determined following OECD Guideline 109 and according to theThe International Pharmacopoeia, Fourth Edition, 2014using Pour and tap density method.The mean pour density and tapped density of the test item was found to be 0.3925 g/cm3and 0.5005 g/cm3 respectively at  28.5oC and 968.8 hPa.

Key value for chemical safety assessment
