key study
Study period:
27 May 2003 - 04 June 2003
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:

Qualifier:
according to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
GLP compliance:
yes
Type of method:
other: preliminary test only
Specific details on test material used for the study:
- Batch: 8191-34
- Purity: 97.8% (expressed as primary amine, % of total)
Key result
Water solubility:
> 1 000 g/L
Temp.:
20 °C
pH:
12.5
Remarks on result:
other: Result obtained in a preliminary test.
Details on results:
All visual observations showed a clear colourless solution without phase separation. The test substance is thus concluded to be miscible with water in at least a 1:1 (w:v) ratio (i.e. water solubility of the test substance is > 1000 g/L) at 19.7 ± 0.6°C. The pH of the aqueous solution was 12.5.
Conclusions:
The substance is concluded to be miscible with water in at least a 1:1 (w:v) ratio (i.e. water solubility of the test substance is > 1000 g/L) at 19.7 ± 0.6°C.  The pH of the aqueous solution was 12.5.

Description of key information

The water solubility of the substance was determined in a GLP study according to test methods EC A.6 and OECD 105 to be >1000 g/L at 20 °C, following a preliminary test with visual observations (Baltussen, 2003).

Key value for chemical safety assessment

Water solubility:
1 000 g/L
at the temperature of:
20 °C

Additional information

The test substance is concluded to be miscible with water in at least a 1:1 (w:v) ratio (i.e. water solubility of the test substance is > 1000 g/L). A pH of 12.5 was measured at this concentration.
