Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Link to relevant study record(s)
- Endpoint:
- boiling point
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- the study does not need to be conducted because the substance is a solid which decomposes before boiling
- Justification for type of information:
- A DSC thermal analysis was conducted under nitrogen atmosphere, after resetting the thermic background of the sample.First scan: -80° to 300°C, where it can be observed a) first peak is observed at -31.20°C that can be interpreted as a passage from the crystalliwn to the amorphous stateb) a second endothermic peak, with a maximum at 189.8°C which can be assumed to be a chemical rearrangement of the substance during melting. In fact the IR analysis of the substance before and after the scanning, especially in the range of vibrations below 1750 cm-1 shows a completely different spectrum, confirming the change in chemical composition.Boiling of the substance is therefore not applicable and adaptations of the information requirements as described in Column 2 of Annex VII of the REACH Regulation can be applied(see attached information)

Description of key information
not required
Key value for chemical safety assessment
Additional information
The thermal behaviour of the substance was tested by DSC from -80° to 300°C showing an endothermic process at 189.8°C before boiling with structural modification. Specific rules for adaptation as decribed in Column 2 Annex VII of the REACH Regulation can be applied and the boiling point determination does not need to be conducted (decomposition before melting).
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.
