Applicant's summary and conclusion
- Conclusions:
- The test item decomposed at approximately 318 ± 1 °C (592 ± 1 K). As the test item decomposed, no value for melting temperature could be determined.
- Executive summary:
The melting point of the test item was determined by differential scanning calorimetry in a valid GLP study according to EU Method A.1 and OECD TG 102.
An aliquot of 0.0051 g was heated from 25.0 to 500 °C with a heating rate of 5.0 °C/min. The test item decomposed from approximately 318 °C (592 K). As the test item decomposed, no value for melting temperature could be determined.
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).
