Conclusions:
The solubility of 1,4-diamino-2,3-dichloroanthraquinone in water was determined as, 0.08 mg/L as High aqueous solubility and 0.035 mg\L as Low aqueous solubility.
Executive summary:

In the present study the water solubility of 1,4-diamino-2,3-dichloroanthraquinone was determined by generator column method. The solubility of 1,4-diamino-2,3-dichloroanthraquinone in water was determined as, 0.08 mg/L as High aqueous solubility and 0.035 mg\L as Low aqueous solubility.

Thus, based on experimental obtained values the substance 1,4-diamino-2,3-dichloroanthraquinone was considered to be insoluble in water.

Additional information

In the present study the water solubility of 1,4-diamino-2,3-dichloroanthraquinone was determined by generator column method. The solubility of 1,4-diamino-2,3-dichloroanthraquinone in water was determined as, 0.08 mg/L as High aqueous solubility and 0.035 mg\L as Low aqueous solubility.

Thus, based on experimental obtained values the substance 1,4-diamino-2,3-dichloroanthraquinone was considered to be insoluble in water.

Other supporting study from EPI Suite (WSKOW v1.42) estimated the water solubility of substance 1,4-diamino-2,3- dichloroanthraquinone at 25 deg C was 0.1104 mg/L.

These estimated value, also supported the selected key value and the substance 1,4-diamino-2,3-dichloroanthraquinone was considered to be insoluble in water.
