Materials and Methods: Differential Scanning Calorimetry
Study period: 26 November 2015 to 16 March 2016
Results: The test item N,N-Dimethyloctan-1-amine has a melting point of -57.2 °C at 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
During the heating phase a
distinct endothermic effect was observed in the temperature range
of-70 – -40 °C, which can be associated with the melting of the test
item. As the onset temperatures in both tests do not deviate by more
than 0.5 K from their mean value of
-57.23 °C, this temperature can be used as freezing point. The test item
has a melting point of -57.2 °C.
Description of key information

Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -57.2 °C
