Any other information on results incl. tables
It was concluded from the results of the DSC and capillary method that the test item showed a weak endothermal effect in the temperature range of 130 °C - 155 °C and a weak exothermic effect in the temperature range of 160 °C - 240 °C but remained solid and unchanged in its visual appearance up to its melting point of 255.8 °C ± 0.5 °C.
Applicant's summary and conclusion
- Conclusions:
- The melting point of the test item was determined to be 255.8 °C +/- 0.5 °C.
- Executive summary:
The test item showed a weak endothermal effect in the temperature range of 130 °C - 150 °C and a weak exothermic effect in the temperature range of 160 °C - 240 °C but remained solid and unchanged in its visual appearance up to its melting point of 255.8 °C ± 0.5 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
