Endpoint:
vapour pressure
Data waiving:
study scientifically not necessary / other information available
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 since the melting point is above 300 deg C.

The mean melting temperature range of Hydrogen [4-[4-(dimethylamino)-α-(2-hydroxy-3,6-disulphonato-1-naphthyl)benzylidene]cyclohexa-2,5-dien-1-ylidene]dimethylammonium, monosodium salt was determined to be 321.3°C -325°C at 976.3hPa. Hence, this endpoint was considered for waiver.

Key value for chemical safety assessment
