Applicant's summary and conclusion
- Conclusions:
- The melting point of the substance is 82°C.
- Executive summary:
The melting point of the substance was determined by DSC using a Mettler Toledo DSC 821e apparatus in the temperature range from 25 - 450 °C.
The heating rate was 3 K/min and the substance was tested in a sealed vial under air.
The melting point was found to be 82 °C.
