Description of key information

- decomposition >250°C, no melting point; OECD Guideline 102; RL1; GLP

- CRC handbook of chemistry and physics the melting point: 235°C.

Key value for chemical safety assessment

Additional information

In the GLP-compliant study conducted according to OECD guideline 102 the final DSC measurements were performed in the temperature range from 20 - 340 °C.

Two  endothermic  peaks  could  be  observed  (peak  maxima:  109  °C/242  °C  [first  run]  resp.  109  °C/ 240 °C [second run]). These two peaks correlate with maxima observed during the thermogravimetric measurement.  Upon  further  heating  the  DSC-curve  showed  no  more  sharp  peaks  but  the  typical fluctuating course of decomposition. Thus, no melting point could be detected, the substance decomposes.
