Description of key information

Preliminary TGA 
 
Instrument: Q50 thermogravimetric analyzer (TGA) (TA Instruments, USA)
Sample container: aluminum, closed with a lid in which a small hole was drilled
 
5.82 mg test substance was heated with a rate of 20°C/minute from 25°C to 401°C. At this point 70% weight loss of the test substance was observed. After the experiment, the sample was cooled to 50°C and the consistency of the test substance was determined.
 
DSC experiment
 
Instrument: Q100 differential scanning calorimeter (TA Instruments, USA)
Sample container: aluminum, closed with a lid in which a small hole was drilled
Reference: empty sample container
 
4.79 mg test substance was heated with a rate of 20°C/minute from 25°C to 374°C.
 
The experiments were performed under a flow of nitrogen and at atmospheric pressure.
