Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
13.9 °C
Atm. press.:
99.4 kPa

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.

Melting point test

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.

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.

Description of key information

The melting point is 13.9 +- 2.3 °C at 99.4 kPa.
