EC number: 239-405-4 | CAS number: 15373-31-6
The melting range of the test substance was determined to be - 32 to - 35 °C at 1013.25 hPa.
A study was conducted according to OECD test guideline 102, Regulation (EC) No 440/2008 method A.1 and EPA OCSPP test guideline 830.7200 to determine the melting point of the test item using differential scanning calorimetry. Two tests with about 10 – 11 mg of the test item were performed. The substance is a liquid at ambient conditions. Therefore the crucibles were cooled down to -100 °C and afterwards the temperature was increased up to 500 °C. During the cooling phase a thermal effect was observed in the temperature range from - 65 to - 60 °C, which was associated with the freezing of the test item. During the heating phase a distinct endothermic effect was observed in the temperature range from – 45 to - 10 °C, which was associated with the melting of the test item. As the onset temperatures in both tests deviate by more than 0.5 K from their mean value of -33.56 °C, the test item had a melting range from - 32 to - 35 °C at 1013 hPa.
