Conclusions:
The water solubility of T002251 at 20°C was determined to be 0.32 g/L and thus moderately soluble.

Description of key information

The water solubility of T002251 was determined to be 0.32 g/L at 20°C in a GLP study according to OECD guideline 105 and EU Method A.6 (K1, Tognucci, 2004). T002251 is considered "moderately soluble".

Key value for chemical safety assessment

Water solubility:
0.32 g/L
at the temperature of:
