Colourless to pale yellow organic liquid (observation associated with studies conducted in accordance with OECD guidelines under GLP conditions)

Key value for chemical safety assessment

Physical state at 20°C and 1013 hPa:

Additional information

Observations in various study reports indicate that the substance is a colourless organic liquid. The freezing point was determined to be -18.8 °C (see section 4.2); the boiling point was determined to be 195 °C (see section 4.3). At intermediate temperatures the substance is expected to be a liquid.
