- Key result
- Melting / freezing pt.:
- 13.9 °C
- Atm. press.:
- 99.4 kPa
- Conclusions:
- The melting point is 13.9 +- 2.3 °C at 99.4 kPa.
- Executive summary:
The melting point of the test item was determined by DSC according OECD guideline no. 102. The melting point is 13.9 +- 2.3 °C at 99.4 kPa.
Reference
The sample shows an endothermic melting peaks in the 10 to 20 °C region (Fig. 1 and Table 1).
Two minor peaks at -14 °C and 5 °C don’t have influence to the macroscopic melting behaviour and
are not considered relevant.

Measurement Onset Peak
°C °C
#1 13,90 16,13
#2 13,86 16,20
The mean onset is selected as giving the best value of the start of melting point. The difference
between the lower onset value and the higher peak value is used to estimate the width of the melting
range.
Description of key information
The melting point is 13.9 +- 2.3 °C at 99.4 kPa.
Key value for chemical safety assessment
Additional information
The melting point of the test item was determined by DSC according OECD guideline no. 102. The melting point is 13.9 +- 2.3 °C at 99.4 kPa.
