Applicant's summary and conclusion
- Executive summary:
The melting point of the test substance was derived from the thermal stability test, conducted with Differential Thermal Analysis.
One endotherm was recorded, attributed to melting, with a peak value of ca 117°C.
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.
