Applicant's summary and conclusion
- Conclusions:
- The melting point of DiBrORMA was determined to be -42.56 °C (OECD 102).
- Executive summary:
The melting point of DiBrORMA was determined using differential scanning calorimetry (DSC). During the heating phase a distinct endothermic effect was observed. The standard deviation from onset temperature in the six tests was 0.663 °C from their mean value of -42.56 °C. The study was conducted in accordance with OECD 102 guidelines and was GLP compliant. Therefore, the study is considered reliable without restrictions.
