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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
The DSC measurements were performed twice.
The heat flow curves show two endothermal peaks with maxima at 68/68 °C (minor peak)
and 151/151 °C (major peak). Reweighing after the measurement the sample had lost
approx. 1 % of its mass. After cooling, the residue looked molten and was discoloured
yellowish.
Due to its small size, the thermal effect at 68 °C cannot be further interpreted. The second
peak at 140/141 °C (extrapolated onset temperature), respectively 151 °C (peak maximum),
represents the melting of the sample.

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.
