Reference
Endpoint:
viscosity
Type of information:
experimental study
Adequacy of study:
key study
Study period:
21-07-2011
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Well performed GLP study in accordance with CIPAC method MT 22. Although the result (0.92 cSt) is just below the minimum measurement limit as specified in the test guideline (1.2 cSt), the test result is considered reliable.
Qualifier:
according to
Guideline:
other: CIPAC method MT 22 1994, reprinted 2007
Deviations:
yes
Remarks:
Result below the minimum measurement limit as specified in the test guideline.
GLP compliance:
yes (incl. certificate)
Type of method:
capillary viscometer (static)
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
Temp.:
20°C
Parameter:
kinematic viscosity (in mm²/s)
Value:
0.92
Remarks on result:
other: The viscosity reported is the mean of 3 results.

Each of the three measurements showed a viscosity of 0.92 mm2/s

The obtained result is below the minimum measurement limit as specified in the test guideline. However, due to the time taken for the sample to pass through the viscometer (approx 300 seconds) it is deemed that the result is valid and accurate.

Conclusions:
The kinematic viscosity of the substance was determined to be 0.92 mm2/s (mean of 3 results) at 20°C.

Description of key information

The kinematic viscosity of the test substance was determined in a GLP study according to CIPAC test method MT 22 to be 0.92 mm2/s at 20 °C, applying a capillary U-tube viscometer (Shajad Younis, 2011)

Key value for chemical safety assessment

Viscosity:
0.92 mm²/s (static)
at the temperature of:
20 °C
