Conclusions:
The water evaporation connected with the beginnig thermal decomposition was observed between 45°C and 245°C. The rapid thermal decomposition of the test substance started at the temperature 295°C. Any peaks correspond to the melting or boiling of the test substance was not observed to the temperature at which the thermal decomposition started.Melting temperature and boiling temperature of the test substance, Reactive Yellow 85, could not be determined because of thermal decomposition of the test substance.
Executive summary:

The melting and boiling temperature of the test substance, Reactive Yellow 85 was investigated. The Differential Scanning Calorimetry method was used.

The procedures used in the study were in accordance with:

Method A.1. Melting/Freezing temperature, Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008

OECD Test Guideline No.102, Melting Point/Melting Range, Adopted July 27, 1995

Method A.2 – Boiling Temperature (1.6.6.2 Differential scanning calorimetry), Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008

OECD Test Guideline No 103, Boiling Point, Adopted July 27, 1995

The water evaporation connected with the beginning thermal decomposition was observed between 45°C and 245°C. The rapid thermal decomposition of the test substance started at the temperature 295°C. Any peaks correspond to the melting or boiling of the test substance was not observed to the temperature at which the thermal decomposition started.

Melting temperature and boiling temperature of the test substance, Reactive Yellow 85, could not be determined because of thermal decomposition of the test substance.

Description of key information

The water evaporation connected with the beginning thermal decomposition was observed between 45°C and 245°C. The rapid thermal decomposition of the test substance started at the temperature 295°C. Any peaks correspond to the melting or boiling of the test substance was not observed to the temperature at which the thermal decomposition started. Melting temperature and boiling temperature of the test substance, Reactive Yellow 85, could not be determined because of thermal decomposition of the test substance.
