Justification for data waiving:
the study does not need to be conducted because the melting point is above 300°C

Description of key information

The study does not need to be conducted because the melting point is above 300°C. The melting point determination of Test item Calcium 3 -hydroxy-4 -[(4 -methyl-2 - sulphonatophenyl)azo]-2 -naphthoate (CAS No. 5281 -04 -9 ) was done as per the test guideline OECD 102. The method followed was according to Capillary/metal block. No change was observed up to 400°C, inferring that the Mean Melting Point was determine to be greater than 400°C at 976.9 hPa.

Key value for chemical safety assessment
