Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Study period:

16 December 2003 and 11 March 2004

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

other: GLP study conducted in accordance with an internationally recognised method

Reason / purpose for cross-reference:

reference to other study

Qualifier:

according to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

GLP compliance:

yes (incl. QA statement)

Type of method:

flask method

Water solubility:

0.375 g/L

Temp.:

20 °C

pH:

3.6

Remarks on result:

other: Organic component as determined by HPLC

Details on results:

The water solubility of 0.376 is obtained by summation of the organic component concentration obtained by HPLC analysis (0.225 g/l) and the inorganic component concentration determined by ion chromatography (0.150 g/l).

Organic component analysed at 24, 48 and 72 hrs = 0.227, 0.225 and 0.224 g/l

Inorganic component analysed at 24, 48 and 72 hrs - 0.151, 0.148 and 0.152 g/l

Conclusions:

Interpretation of results (migrated information): moderately soluble (100-1000 mg/L)
The water solubility of MPP has been determined as 0.375 g/l at 20°C.
