Results and discussion
Any other information on results incl. tables
The thermal stability of the test substance was evaluated using thermogravimetry according to MATGA-02001 (internal method). Around 20 mg of the test substance were heated under Argon from 25 to 1 000 °C at 10 °C/min heating rate. Two replicates were performed on ground sample. The table below summarizes the successive mass losses observed. Max DTG is the temperature at witch the mass loss velocity is maximal. The total mass loss at the end of the experiment is 25.7 %.

Applicant's summary and conclusion
- Conclusions:
- No melting and boiling points could be measured because the test substance decomposes before melting.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
