melting point/freezing point
Type of information:
experimental study
Adequacy of study:
key study
Study period:
16 April 2018 to 23 July 2018
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
Version / remarks:
27 July 1995
GLP compliance:
yes (incl. QA statement)
Other quality assurance:
ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Identification: Photomer 4250
Appearance: Colourless to pale yellow liquid
Key result
Melting / freezing pt.:
-60.8 °C
Atm. press.:
ca. 1 013 hPa
No melting point was determined. A glass transition of the test item was obsserved at -60.8C (212.3K).

Executive summary:

In this guideline (OECD 102) study, conducted with GLP certification, no melting point of the test substance (EC 946 -043 -7) was determind.

Description of key information

Study conducted to recognised testing guidelines with GLP certification
