Mean Concentration: 8.64 x 10-2 g/l at 20.0 +/- 0.5 degrees C

Range:                       8.35 x 10-2 to8.95 x 10-2 g/l

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
Water solubility of the test material was determined to be 8.64 x 10-2 g/l using the flask method and GC analysis.
Executive summary:

Water Solubility: A value of 8.64 x 10-2g/l at 20.0 degrees C +/- 0.5 was determined for the test article using the Flask method (Method A6 Water Solubility of Commission Regulation (EC) No. 440/2008 of 30 May 2008 and Method 830.7840 of the OPPTS Guideline).
