Description of key information
Freezing Temperature ( OECD 102, EU Method A.1., ISO 1392) The melting/freezing temperature is < -22 °C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -22 °C
Additional information
The melting/freezing point of the test substance was determined using the method:Determination of the crystallizing point, according to ISO 1392.
The test substance did not solidify down to -22 °C. Identical observations were made in both samples.
The melting/freezing temperature ofdibutylfumarateis < -22 °C.
Freezing temperatures below -20 °C was not determined, according to the Guidance on information requirements and chemical safety assessment, Chapter R.7a: Endpoint specific guidance, May 2008, ECHA.
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).
