Materials and methods
Test guideline
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Approximately 5 mg of the substance was sealed inside a 40 l aluminium crucible with a pinhole in the lid. This was then placed into a DSC cell which was cooled by liquid nitrogen. Because the melting/freezing takes place over a large temperature range including several peaks, an interval is
reported. Temperature program:From -100 to 30 ºC at a rate of 5 ºC per minute - GLP compliance:
- no
- Type of method:
- other: Differential Scanning Calorimetry
