Type of information:

experimental study

Adequacy of study:

key study

Study period:

18 Jan-28 Jun 1991

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Remarks:

Also according to GLP.

Qualifier:

according to guideline

Guideline:

EU Method A.6 (Water Solubility)

Version / remarks:

1984

GLP compliance:

yes

Type of method:

column elution method

Water solubility:

< 0 g/L

Temp.:

20 °C

pH:

5.7

Results:

Test sample	Measured peak height (mm)	Water solubility (μg/mL)	Water solubility (g/L)	pH
1	5	<0.05230	<5.2 x 10^-5	5.70
2	5	<0.05230	<5.2 x 10^-5	5.80
3	4	<0.05230	<5.2 x 10^-5	6.13
4	3	<0.05135	<5.1 x 10^-5	5.92
5	4	<0.05230	<5.2 x 10^-5	5.88

pH of blank solution: 6.00, 5.92 and 6.30

Conclusions:

Interpretation of results: insoluble (< 0.1 mg/L)
The water solubility of the test item at 20°C and pH = 5.7 was < 5.2 x 10-5 g/L

Executive summary:

The water solubility of the test item was determined according to the EC A.6 method in compliance with GLP. The solubility was below the detection limit for all measurements. It was therefore concluded that the water solubility of the test item was < 5.2 x 10 -5 g/L.

Description of key information
