Conclusions:
T003422 appears to be very soluble in dichloromethane, toluene, tetrahydrofuran (> 200 g/L) and ethyl acetate and methyl ethyl ketone (220 g/L)..

Description of key information

In a non-GLP study the solubility of T003422 in different organic solvents was determined at 20°C. No specific guideline was followed, instead a comparable method is used. For this reason, the study is assigned as reliable with restrictions (Klimisch score 2). Based on the results, T003422 appeared to be very soluble in dichloromethane, toluene, tetrahydrofuran (> 200 g/L) and ethyl acetate and methyl ethyl ketone (220 g/L).

Key value for chemical safety assessment
