- Decomposition:
- no
- Conclusions:
- The melting point of the test substance was determined to be 135.3 °C (408.4 K) at 100.1 to 100.2 kPa.
- Executive summary:
The study was performed to determine the melting temperature of the test item according to OECD TG 102 and EC MEthod A.3 and in compliance with GLP. Using the differential scanning calorimetry method, the mean melting temperature of the test substance was determined to be 135.3 °C (408.4 K) at 100.1 to100.2 kPa ffrom the four determinations performed. The relative standard deviation for the performed measurements was 0.40 %.

RESULTS
The mean melting temperature of the test item was 135.3 °C (408.4 K). A standard deviation of 0.54 °C was obtained from the four replicate determinations performed, resulting in a percentage relative standard deviation of 0.40 %. Atmospheric pressure: 100.1 to 100.2 kPa. Essentially identical thermograms were observed in both air and a nitrogen atmosphere. A change in appearance for the remaining residue, that of an amber colored solid, as opposed to returning to a white colored solid, was observed during all determinations.
