- Endpoint:
- boiling point
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because chemical change occurred during the melting point study

- JUSTIFICATION FOR DATA WAIVING
In accordance with REACH Regulation (EC) No. 1907/2006 Annex VII, column 2 section 7.3 the study does not need to be conducted for solids which either melt above 300 °C or decompose before boiling. In such cases the boiling point under reduced pressure may be estimated or measured, and/or for substances which decompose before boiling (e.g. autooxidation, rearrangement, degradation, decomposition, etc). Based on available information consisting of: preliminary TGA and DSC measurements for Melting Point in accordance with OECD TG 102, the substance was observed to decompose at ca. 237 °C (510K) prior to melting. According to ECHA Guidance on Information Requirements and Chemical Safety Assessment (Chapter R.7a: Endpoint Specific Guidance, R.7.1.3, July 2017) the study does not need to be conducted as chemical change was observed during the melting point study.

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).
