Applicant's summary and conclusion
- Conclusions:
- The melting point of the test item is 340°C
- Executive summary:
The DSC shows a sharp exothermic peak at 340°C as melting point.
No exothermic decomposition was observed, but the change in appearance indicates that a non-exothermic decomposition takes place on melting.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
