The melting point was determined at -111.2°C. During cooling a freezing point was detected at -131.2°C, however whereas the melting point was well defined with a moderate heating rate, the determined freezing point is afflicted with the effect of a supercooled liquid and depended on the cooling rate, which was not controlled. The recorded melting point is therefore reported as the key result.

Conclusions:
The melting point for the 2-bromo-3,3,3-trifluoropropene sample was determined at -111.2 °C.
