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
Conclusions:
The study does not need to be conducted, because the given substance Aluminium, 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl)azo]-1H-pyrazole-3-carboxylic acid complex is a solid compound and it was experimentally reported that it melts at temperature of 365.5-370°C hence this vapor pressure endpoint study was considered for waiver.
Executive summary:

The study does not need to be conducted, because the given substance Aluminium, 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl)azo]-1H-pyrazole-3-carboxylic acid complex is a solid compound and it was experimentally reported that it melts at temperature of 365.5-370°C hence this vapor pressure endpoint study was considered for waiver.

Description of key information
