Applicant's summary and conclusion

Executive summary:

The water solubility of androstanolon-acetat was determined in “pretest quality” to be

0.003 g/l

using a screening method based on the detection of the beginning of precipitate formation upon portion-wise addition of an organic solution of the respective test substance under continuous stirring into an excess volume of water while maintaining a temperature range of 25 to 30 °C.

Due to the specifics of the screening method, the above value is expected to represent an upper limit which should not be exceeded by the test substance in its crystalline form.

Androstanolon-acetat is to be considered as practically insoluble or insoluble in water.
