- Executive summary:
The test item has a melting point of -68.3 °C corected to normal atmospheric pressure (1013 hPa) as determined by differential scanning calorimetry according to Regulation EC No. 440/2008 Method A.1. and OECD Test Guideline 102 (1995).
Reference
A distinct endothermic effect was observed in the temperature range of -75 to -50 °C, which can be associated with the melting of the test item. As the onset temperatures in both test do not deviate by more than 0.5 K from their mean value of 68.31 °C, this temperature can be used as melting point. The test item has a melting point of 68.3 °C
