Link to relevant study record(s)

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

05 Nov to 25 Nov 2014

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Reason / purpose for cross-reference:

reference to other study

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

GLP compliance:

no

Type of method:

differential scanning calorimetry

Melting / freezing pt.:

< -70 °C

Atm. press.:

1 013 hPa

Procedure

For DSC measurement the liquid test substance is cooled with liquid nitrogen. The measurement is carried out in an atmosphere of nitrogen (30 ml/min). During the cooling step the measurement starts at 0 °C (approx. 273 K), cooling took place at a rate of 5 K/min down to -70°C (approx. 203 K) followed by heating from -70°C (approx. 203 K) up to 0°C (approx. 273 K).

Results

Test	Melting/Freezing temperature
1	< -70°C
2	< -70°C
Mean value	< -70°C, < 203 K

 

The DSC diagrams show no melting / freezing temperature.

Conclusions:

A melting point value of <-70 °C at 1013 hPa was determined in a reliable study conducted according to an appropriate test protocol. It was not compliant with GLP.
