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

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Deviations:

no

Qualifier:

according to guideline

Guideline:

OECD Guideline 102 (Melting point / Melting Range)

Deviations:

no

GLP compliance:

yes (incl. QA statement)

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 substance showed no change in appearance 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.
