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
