Executive summary:

In this study conducted to generally recognised scientific standards, the boiling point of the test substance (EC 404-363-3) could not be determined as it decomposed at ≥275°C before boiling.

Description of key information

Study conducted to generally recognised scientific standards.

Key value for chemical safety assessment

Additional information

The boiling/decomposition point was estimated using data by TGA measurements.

Additionally, the boiling point was measured to be 185°C at 11 Pa (related to report on vapour pressure curve)

Decomposed at >275°C before boiling.
