Applicant's summary and conclusion

Conclusions:
The study was performed according to DIN 51004 with acceptable restrictions (no GLP) and therefore reliability of Klimisch 2 has been assigned. The substance melts at ca. 204°C.
Executive summary:

The melting point of the test substance was determined to be 204 °C in a non-GLP test according to DIN 51004 using the DTA method. This technique records the difference of the temperature of a substance and an empty measuring cell. The substance and reference cell were subjected to the same controlled temperature programme. The melting point was detected as a characteristic endothermic peak. The sample (10.7 mg, 16.1 mg and 12.3 mg) was heated in a glass vessel at a linear rate of 1 K/min. The measurement was recorded electronically.
