GUIDELINE
The investigation was performed by differential scanning calorimetry using a method designed to be compatible with OECD 102 (27 July 1995) and Method A.1 Melting/Freezing Temperature of Commission Regulation (EC) No 440/2008 (30 May 2008).
RESULTS
The melting/freezing point of the test item was determined to be 99 to 124 °C (372 to 397 K).

RESULTS
- Thermograms and thermographic data for Determinations 1 and 2 are shown in Figures 1 and 2 (attached).
- Broad endotherms were observed at atmospheric pressure of 102 kPa and these were interpreted as melting ranges of 103 to 124 °C (Determination 1) and 99 to 124 °C (Determination 2).
Description of key information
The melting/freezing point of the test item was determined to be 99 to 124 °C (372 to 397 K) (OECD 102 and EU Method A.1).
Key value for chemical safety assessment
