- Key result
- Melting / freezing pt.:
- 118.5 °C
- Conclusions:
- The mean melting point of the test substance, desmedipham, is 118.5°C.
- Executive summary:
The melting point of desmedipham was carried out by differential scanning calorimetry (DSC). The melting point of desmedipham is 118.5°C.
Reference
The DSC was carried out by Mettler-Toledo TA8000. For a preliminary test on thermal stability a DSC in a closed glass pan was performed. At 119°C a melting of the test substance and at about 225°C an exotermic effect was observed. The determination of the melting point / melting range by DSC was carried out in closed standard aluminium pan (Table 1).
Description of key information
The melting point of desmedipham was carried out by differential scanning calorimetry (DSC). The melting point of desmedipham is 118.5°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 118.5 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
