Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
no
Type of method:
differential scanning calorimetry
Key result
Melting / freezing pt.:
>= 8 - <= 13 °C
Atm. press.:
101.3 kPa
Decomposition:
no

The sample shows an endothermic melting peak in the 5 to 18 °C region.

Just before the exothermic peak there is an exothermic relaxation peak. This indicates that the

sample was trapped in a glassy state on cooling. On raising the temperature crystallisation occurred.

 Measurement  Onset / °C Peak / °C 
 #1  7.4  12.5
 #2  8.6  13.1

The mean onset is selected as giving the best value of the start of melting and the mean peak the end of melting.

The melting point of the test item is 8 - 13 °C.

Description of key information

Melting range (DSC): 8 - 13 °C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
8 °C

Additional information

The melting point of the test item was determined by DSC according OECD guideline no. 102 to be 8 - 13 °C.
