Conclusions:
The melting point determination of Disodium 6-hydroxy-5-[(4- sulphonatophenyl)azo]naphthalene-2-sulphonate (CAS No. 2783-94-0) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and Mean decomposition range was found to be 390.0-393.7°C at 972.8hPa.
