Method Details		Observations
Method	Freezing temperature determination according to Cooling Curve method using MicroLab FS-524	-
Principle of Freezing Point test	The freezing point of a pure sample is determined by making measurements of the temperature as a function of time while the sample is submerged in a constant temperature bath at a temperature below that of the expected freezing point of the sample. The data (Temperature vs. time) is plotted; this plot is known as a cooling curve. The freezing point is the value of temperature in the flat portion of the curve.	-

Conclusions:

The Freezing point of Isopentyl Benzoate; CAS No. 94-46-2 was determined with Freezing Temperature Method and it was determined to be less than -13.54 °C at 981.2 hPa.

Executive summary:

The Freezing point determination of Isopentyl Benzoate (CAS No.94-46-2) was done using crushed ice and salt. No freezing was observed up to -13.54°C. Hence, the freezing point was inferred to be less than -13.54°C at 981.2 hPa.
