Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:
experimental study
Adequacy of study:
key study
Study period:
From May 23rd, 2018 to May 24th, 2018
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
July 1995
according to guideline
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
method to determine freezing temperature
Key result
Melting / freezing pt.:
< -35.7 °C
Remarks on result:
It is assumed that the test was performed under atmospheric pressure.

It was confirmed that the test item does not achieve the freezing point until -35.7 °C. Further cooling was not performed. The results are shown in Fig 1. The graph was created using Microsoft Excel 2016.

The freezing point of the test item is <-35.7ºC.
Executive summary:

The determination of the freezing point of the test item was carried out in accordance with OECD Guideline No. 102 "Melting Point/Melting Range" in conformity with the EEC method A.1, under GLP conditions.

The test item was deposited in a test tube which was placed in an outer tube and set in a Dewar vessel containing the freezing mixture. The test item was stirred and the temperature recorded during cooling. The freezing point of the test item was determined to be <-35.7ºC. Further cooling was not performed.

Description of key information

Key study. Method according to OECD 102 and EU A.1, GLP study. The test item has a freezing point <-35.7ºC.

Data waving (study scientifically not necessary / other information available): According to Annex VII column 2 of REACH Regulation, the study does not need to be conducted below a lower limit of -20ºC.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-35.7 °C
