Applicant's summary and conclusion
- Conclusions:
- The melting point of the substance is 249°C.
- Executive summary:
The melting point of the substance was determined by DSC using a Mettler Toledo DSC 823e calorimeter. The heating range was 25- 400 °C, the heating rate was 10 K/min and a aluminum pale with hole was used. The melting point was found to be 249°C; at 265° C the substance started to decompose.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
