Results and discussion
Melting / freezing point
- Key result
- Melting / freezing pt.:
- -15.5 °C
- Atm. press.:
- 985 hPa
Any other information on results incl. tables
During the heating phase a distinct endothermic effect was observed in the temperature range of -30 to 20 °C, which can be assigned to the melting of the test item. As the onset temperatures in both tests deviate by less than 0.5 K from their mean value of -15.45 °C, this temperature can be used as melting point.
Applicant's summary and conclusion
- Conclusions:
- The melting point of MDP was determined to be -15.5 °C at 985 hPa (OECD 102).
- Executive summary:
The melting point of MDP was determined using differential scanning calorimetry (DSC). During the heating phase a distinct endothermic effect was observed. The onset temperature in both tests deviate by less than 0.5 K from their mean value of -15.45 °C. The study was conducted in accordance with OECD 102 guidelines and was GLP compliant; therefore the study is considered reliable without restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
