Conclusions:
The water solubility determination of test item was done as per the OECD guideline 105 byspectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 10.602 g/L at 25°C.
Thus test chemical is considered to be very soluble in water.
Executive summary:

The water solubility determination of test item was done as per the OECD guideline 105 byspectrophotometric analytical method as per OECD 101. The solubility of test chemical in water was determine to be 10.602 g/L at 25°C.

Thus test chemical is considered to be very soluble in water.
