The following is understood in a canonical manner, and attempts to answer it from a chemical point of view.
2 - [ (4-hydroxy-9,10-dioxide-9,10-dihydroanthracene-1-yl) amino] - 5 -methylanthraquinone sulfonic acid, this compound has the following physical properties:
1. ** Appearance and properties **: Usually, such compounds containing anthraquinone structure are mostly solid forms. Due to the presence of conjugated systems in the molecule, they may exhibit certain colors, such as yellow and orange. In ancient Chinese, "its shape is usually solid, and its color may be yellow or orange, due to the system of intra-molecular conjugation".
2. ** Solubility **: In view of the fact that there are both hydrophobic anthraquinone skeletons and hydrophilic sulfonic acid groups, amino groups, hydroxyl groups and other groups in the molecule. It should have a certain solubility in water, because the sulfonic acid group can form a strong interaction with water molecules; and it may also have good solubility in organic solvents such as ethanol and acetone, because the anthraquinone skeleton has a certain lipophilicity. "It is soluble in water because of the base of sulfonic acid; it is also soluble in organic solvents such as ethanol and acetone, and the lipophilicity of anthraquinone."
