Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
589 K

Additional information

In the key study Butler & White (2008), the melting/freezing point of the test material was determined under GLP conditions in accordance with EU Test Method A1, using the differential scanning calorimetry (DSC) procedure specified in ASTM E537-86. This study was assigned a reliability score of 1 in line with the principles for assessing data quality as defined by Klimisch et al (1997).

Under the conditions of the test, the test material decomposed with melting at 589 ± 0.5 K (316 °C).
