guideline study
according to guideline
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
yes (incl. QA statement)
Type of method:
method to determine freezing temperature
Specific details on test material used for the study:
- Name of test material (as cited in study report): MOPA, 3-methoxypropylamine
- Physical state: Liquid
- Analytical urity: 99.4% by GC
- Purity test date: 12-04-2010
- Lot/batch No.: 9M603
Key result
Melting / freezing pt.:
< -20 °C
Remarks on result:
other: Atmospheric pressure not reported; ambient conditions are anticipated

In both runs no crystallisation was observed down to -25°C, therefore the test was terminated.

The freezing temperature of the substance was concluded to be below -20°C under ambient conditions.

Description of key information

The freezing point of the test substance under ambient conditions was determined to be below -20°C in a GLP study according to test method EC A.1 (Shajad Younis, 2011).

Key value for chemical safety assessment

Additional information

The freezing point of the test item was determined to be <-20°C.
