Test material decomposition was observed beginning at approximately 219 °C (492 K) prior to melting at 258 ± 1 °C (531 ± 1 K) by differential scanning calorimetry and visual assessment.

Conclusions:
Under the conditions of the study, decomposition of the test material was observed beginning at approximately 219 °C (492 K) prior to melting at 258 ± 1 °C (531 ± 1 K) by differential scanning calorimetry and visual assessment.
Executive summary:

Under the conditions of the study, decomposition of the test material was observed beginning at approximately 219 °C (492 K) prior to melting at 258 ± 1 °C (531 ± 1 K) by differential scanning calorimetry and visual assessment.

Description of key information

Under the conditions of the study, decomposition of the test material was observed beginning at approximately 219 °C (492 K) prior to melting at 258 ± 1 °C (531 ± 1 K) by differential scanning calorimetry and visual assessment. (As the test material decomposed prior to melting, the boiling point was not determined).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
258 °C
