Endpoint:
boiling point
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance is a solid which decomposes before boiling

Description of key information

The study does not need to be conducted because the substance is a solid which decomposes before boiling. According to Column II of Annex VII, the boiling point study does not need to be conducted for solids which either melt above 300 °C or decompose before boiling. Test substance is a solid at room temperature and it is starts to decompose at a  temperature of  252 °C and complete decompostion at 258.5 °C .Hence, it is not feasible to determine boiling point and the endpoint was considered for waiver.

Key value for chemical safety assessment
