- Key result
- Melting / freezing pt.:
- 88 - 101 °C
- Conclusions:
- The test item MCC-5424/18 shows a melting area of crystalline subcomponents between 88 °C and 101 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination).
Reference
To determine the melting behaviour (three independent single measurements), the test item was measured by DSC between -90 °C and 150 °C with a heating / cooling rate of 10 K/min in 3 cycles. For the measurement a capsulated crucible was used.
The test item MCC-5424/18 shows a melting area of crystalline main components between 88 °C and 101 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination). Additional the test item shows a melting of a sub component at 34 °C.
Melting of main component (2nd heating run)
88 °C and 102 °C (from first measurement)
88 °C and 101 °C (from second measurement)
88 °C and 101 °C (from third measurement)
The cooling runs show crystallization.
Description of key information
The test item MCC-5424/18 shows a melting area of crystalline subcomponents between 88 °C and 101 °C according to the definition in the OECD Guideline 102 (mean value from repeat determination).
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 88 °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.
