- Executive summary:
Method
The test was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method for the analysis.
Result
The substance shows a negative peak on the release of water/ solvent between 25 and 180 °C, followed by a degradation that begins at 218 °C.
Reference
The substance shows a negative peak on the release of water/ solvent between 25 and 180 °C followed by 4 peaks that describe the degradation of the product starting at 218 °C.
Description of key information
The substance decomposes before melting above 218°C.
Key value for chemical safety assessment
Additional information
The assessment was performed with one screening study and two DSC analyses
The study performed in 1989 is a screening study with unknown method; the purity is about 78 %.
The study conducted in 1988 is a DSC analysis performed with a method similar to European guideline A.1. The purity is about 78 %. The DSC shows the endothermic peaks that could be related with melting and boiling point.
The first peak is not a characteristic endothermic peak related to melting point, but it is associated to the release of water/ solvent, followed by a boiling point located between 200 and 253 °C.
These informations supports the data inserted into the key study conducted with The guideline OECD 102. The composition is completely identified (all information are inserted into the IUCLID section 1.2 and 1.4).
The substance shows a negative peak connected to the release of water/ solvent between 25 and 180 °C followed by 4 peaks that describe the degradation of the product starting at 218 °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).
