Additional information

The substance is an amorphous solid at room temperature. No endothermic peak consistent with a melting point was observed in the DSC plot (see Section 4.3, Boiling Point) between room temperature and the decomposition temperature onset at 259.1°C. As a result, the freezing point was determined in a guideline study, after heating to 80°C and cooling to 6.4°C, indicating significant hysteresis (the substance is normally a solid at room temperature).
