Executive summary:

A study was conducted to determine the melting point / freezing point of the test substance according to OECD Guideline 102. The experiment was performed using a Differential Scanning Calorimetry method, on a Mettler DSC 1, under nitrogen atmosphere (20 mL/min). 11.6 mg of test substance was placed in a 40 µL aluminium cup. The temperature programming covered the range -30 to 300ºC with a heating rate of 5ºC/min. Under the study conditons, the melting point temperature of the test substance was found to be 104ºC with a range of 95 to 104ºC (Börjesson, 2012).

Description of key information

The melting point was determined according to OECD Guideline 102 (DSC) (Börjesson, 2012)

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
