- STORAGE CONDITIONS OF TEST MATERIAL
Refrigerator (between 0 and 10 °C under nitrogen) - Key result
- Atm. press.:
- 98 kPa
- Decomposition:
- yes
- Decomp. temp.:
- 240 °C
- Remarks on result:
- not determinable
- Remarks:
- decomposes before boiling
- Executive summary:
The boiling point of the test substance was determined under GLP according to OECD 103/EU A2 guideline, Siwoloboff (capillary) method.
Two main runs were performed, and the mean final temperature was retained.
The test substance has been determined to decompose, based on colour change, from 513 K (240 °C) at 98.0 kPa, prior to boiling. The decomposition was confirmed by DSC.

Description of key information
The substance starts to decompose from ca 240°C (based on colour change) before boiling.
Key value for chemical safety assessment
Additional information
A reliable experimental study, conducted according to a recognized OECD/EC method and under GLP, is available. Despite minor restrictions on accuracy, it is considered as a key study. As the substance decomposes prior to boiling, no value is retained as key data.
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).
