Conclusions:
The experimental water solubility of Solvent Red 1 at 25°C was determined 3.3x10-4mg/l
Executive summary:

The experimental water solubility of Solvent Red 1 at 25°C was determined 3.3x10-4mg/l.

This value suggests that Solvent Red 1 is insoluble in water.

Description of key information
