Referenceopen allclose all
When heating a sample of the test substance in an open test tube (10*100 mm) with a gas burner, the compound showed no bubbles or other signs of melting, boiling or decomposition till 400°C. The test substance was only compacted a bit at 240°C.
Description of key information
Key study: OECD 102. The melting point was determined to be > 445ºC.
Supporting study: CRC Handbook. The melting point of the test item is 900ºC.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 445 °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.
