- Melting / freezing pt.:
- 113.2 °C
- Remarks on result:
- other: Test item was a black to brownish solidified melt.
- Conclusions:
- The test item had a mean melting point of 113.2°C.
- Executive summary:
The aim of the test was to determine the melting point of the test item according to the OECD 102 guideline/ A.1 method (Differential scanning calorimetry) and following GLP.
The test item had a mean melting point of 113.2°C.
Reference
Three DSC measurements with a heating rate of 10 l/min showed an endothermal effect (melting) in the temperature range of 95 - 130°C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline and ranged from 112.90 to 113.61°C (Test item was a brownish solidified melt, no mass loss; Test item was a black solidified melt,mass loss: from 58% to 61%).
Description of key information
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 113.2 °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.
