EC number: 456-350-3
CAS number: 878665-13-5
Starting temperature: 294 K (det.1) and 298 K (det.2)
Individual measurements: (1) 292 K, (2) 292 K.
The test material remained unchanged until 288 K, then a crystal of test
material was added to the supercooled liquid to initiate the
Transition occurs within accuracy limits, therefore freezing temperature
will be expressed as a single value.
The freezing point of the test substance was
determined according to OECD/102/EU A1 guideline, using BS4633 method
for the determination of crystallizing point.
The determination was carried out in
duplicate, with seeding to initiate crystallisation.
A freezing temperature of 292 +/- 0.5K (19
+/- 0.5 °C) was determined for the test material.
Freezing point is borderline to ambient temperature.
A fully reliable experimental study on
freezing point measurement, conducted according to a recognized OECD/EU/BS
method and under GLP, is available. It is considered as a key study, the
result is considered as key data.
seeding was used to initiate crystallisation, the substance may be
observed whether as a low melting solid, or a subcooled liquid.
