Description of key information

Melting range: 170.2 ºC – 177.7 ºC (with thermal decomposition), OECD 102, EU method A.1, EPA OPPTS 830.7200 capillary method, Das 1998

Key value for chemical safety assessment

Additional information

The melting behaviour of the test material was determined in accordance with standardised guidelines OECD 102, EU Method A.1 and EPA OPPTS 830.7200 using the capillary method with photocell detection. The test material was found to melt with thermal decomposition, the level of which influences the temperature range within which melting occurs. The melting range was determined to be 170.2 ºC to 177.7 °C.

The study was performed in line with GLP and accepted standardised guidelines with a high standard of reporting. The study was assigned a reliability score of 1 in accordance with the principles of assessing data quality outlined in Klimisch (1997), and considered suitable for assessment as an accurate reflection of the test material.

The available data are considered to be complete and the result determined, melting range 170.2 ºC to 177.7 °C (with thermal decomposition), was carried forward for risk assessment.
