Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

experimental study
Adequacy of study:
key study
Study period:
2003-02-26 to 2003-06-05
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
OECD Guideline 102 (Melting point / Melting Range)
GLP compliance:
yes (incl. QA statement)
Report represents data generated in the “spirit of” Good Laboratory Practice. GLP deviations were that a Study Plan was not written, however Study-Specific Supplements were provided to study personnel describing laboratory work in detail.
Type of method:
method to determine freezing temperature
Specific details on test material used for the study:
- Name of the test material (as cited in the study report): Jeffcat ZF-10, 2-((2-(2-(dimethylamino)ethoxy)ethyl)methyl-amino)-ethanol
- Substance type: Amine
- Physical state: Clear colourless liquid
- Analytical purity: 99%
- Lot/Batch No.: 324756
- Storage condition of test material: 22 °C in the dark
Key result
Melting / freezing pt.:
-53 °C
The freezing point was determined to be - 53°C.

Description of key information

The freezing point was determined to be -53°C according to the OECD guideline 102 test performed by BC Research Inc. (2003). The study was considered to be reliable without restrictions (Klimisch 1).

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-53 °C

Additional information

The freezing point of the test item was determined to be -53 °C.
