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. Based on prediction done using MPBPVP v1.43,the melting point of disodium [μ-[[7,7'-iminobis[4-hydroxy-3-[[2-hydroxy-5-sulphamoylphenyl]azo]naphthalene-2-sulphonato]](6-)]]dicuprate(2-)was  estimated to be 350 Deg C.

Key value for chemical safety assessment

Additional information

The study does not need to be conducted because the melting point is above 300°C. Based on prediction done using MPBPVP v1.43,the melting point of disodium [μ-[[7,7'-iminobis[4-hydroxy-3-[[2-hydroxy-5-sulphamoylphenyl]azo]naphthalene-2-sulphonato]](6-)]]dicuprate(2-)was  estimated to be 350 Deg C.
