3-(methylthio)propionaldehyde

Water solubility

Link to relevant study record(s)

Reference

Endpoint:

water solubility

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

study well documented, meets generally accepted scientific principles, acceptable for assessment

Qualifier:

equivalent or similar to guideline

Guideline:

OECD Guideline 105 (Water Solubility)

Deviations:

no

GLP compliance:

no

Type of method:

flask method

Key result

Water solubility:

ca. 16.3 vol%

Temp.:

25 °C

pH:

ca. 7

Details on results:

The pH of the test solutions is not reported. Therefore a default value of pH 7 is assumed, because MMP has no acid/base relevant functional groups.

Temperature [°C]	% volume of MMP dissolved
25	16.3
17.5	19.03
10	22.0

 

At 25 °C the water solubility was determined to be 16.3 % (v/v). Based on the density of 1.03 g/cm³ from the key study for the endpoint density the water solubility corresponds to ca. 170 g/L.

5	28 (very imprecise)

Conclusions:

At 25 °C MMP has a solubility in water of 16.3 % v/v, corresponding to ca. 170 g/L. MMP is very soluble in water.

Description of key information
