- -13 °C
- Atm. press.:
- 101.325 kPa
- Decomposition:
- no
- Conclusions:
- Under the conditions of this study, the melting temperature of the test substance, Solvent Red 19E, is -13 °C.
- Executive summary:
The melting temperature of the test material was investigated using methodology equivalent to that outlined in the standardised guidelines OECD 102 and EU Method A.1 using Differential Scanning Calorimetry (DSC).
A DSC-curve was recorded during the experiment. No crystallization peak on the cooling curve was detected. The heating curve showed a broad endothermic peak approximately at -18.6 to -1.1 °C. The extrapolated onset temperature of the endothermic peak was -13.01 °C.
Extended uncertainty of determination is ± 1 °C. Extended uncertainty was calculated by using a coverage factor of 2.
Under the conditions of this study, the melting temperature of the test substance, Solvent Red 19E, is -13 °C.
