Applicant's summary and conclusion
- Conclusions:
- The test substance was found to melt, with decomposition, at 144.5 to 146.0 °C.
- Executive summary:
The melting temperature of the test substance was determined with the metal block method according to OECD Guideline 102. The procedure was performed in duplicate using fresh sample material.
The test substance was found to melt, with decomposition, at 144.5 to 146.0 °C under normal atmospheric pressure.
