Endpoint:
melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
25-06-2018 to 29-06-2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: Guideline study performed under GLP. All relevant validity criteria were met.
Qualifier:
according to
Guideline:
EU Method A.1 (Melting / Freezing Temperature)
Deviations:
no
Qualifier:
according to
Guideline:
OECD Guideline 102 (Melting point / Melting Range)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Remarks:
inspected: July 2017 ; signature: November 2017
Type of method:
capillary method
Melting / freezing pt.:
< 253 K
Atm. press.:
1 atm
Decomposition:
no
Sublimation:
no
Remarks on result:
other: < -20 ± 0.5 °C (freezing temperature); mean (n=2)

Measured temperatures were converted from °C to K using T = t + 273.15

T = temperature (K)

t = temperature (°C)

Definitive test:

Overall result; mean (n=2) : less than -20°C (<253 K) ; the test item showed no change in appearance during cooling. Described as a mobile liquid during cooling.

Conclusions:
The freezing temperature of the test item has been determined to be less than 253 ± 0.5 K or less than -20 ± 0.5 °C. The melting point is less than 253 K or less than -20°C.
Executive summary:

The freezing temperature of the test item was determined using EU Method A.1 and OECD TG 102 capillary method under GLP. In a definitive test performed in duplicate the freezing point was determined less than -20 ± 0.5 °C (or less than 253 ± 0.5 K). Applicant assessment indicates since the test item was observed to flow as a liquid at temperatures > -20 °C; the test item melting point can be considered to be < -20 °C. At temperatures greater than or equal to -20 °C (or 253 K) the test item is a liquid at atmospheric pressure.

Additional information

Key study : EU Method A.1, 2018 : The freezing temperature of the test item was determined using EU Method A.1 and OECD TG 102 capillary method under GLP. In a definitive test performed in duplicate the freezing point was determined less than -20 ± 0.5 °C (or less than 253 ± 0.5 K). Applicant assessment indicates since the test item was observed to flow as a liquid at temperatures > -20 °C; the test item melting point can be considered to be < -20 °C. At temperatures greater than or equal to -20 °C (or 253 K) the test item is a liquid at atmospheric pressure.
