Applicant's summary and conclusion
- Executive summary:
The melting and boiling temperature of LEE011-A2 were determined using DSC.
The melting temperature of the test substance was 133°C (406 K).
Reaction and/or decomposition of the test substance was observed at temperatures of > 175°C (> 448K). Boiling of the test substance was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test substance has no boiling temperature.
