Reference
Endpoint:
stability in organic solvents and identity of relevant degradation products
Type of information:
experimental study
Adequacy of study:
key study
Study period:
23 Apr 2010
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Acceptable, well-documented study report which meets basic scientific principles.
Principles of method if other than guideline:
Stability in organic solvents by UV-vis spectrometry
Test substance stable:
yes

The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.

Intensive stirring is necessary for a homogeneous dispersion. About 4 hours is necessary to get a homogeneous dispersion.

Conclusions:
The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.
Executive summary:

The stability of the test substance in organic solvents was determined by UV-vis spectrometry.


The test substance is stable and homogeneous for more than 72 hours in DMSO (0.1 and 50 mg/mL) and in 1,2-propylene glycol (0.1 and 50 mg/mL) at room temperature.
