The potassium salt of 1-amino-9,10-dihydro-4- (5- ((2-hydroxyethyl) sulfonamido) -3,4-xylene-amine) -9,10-dioxo-anthracene-2-sulfonate is a rather special chemical substance. Its physical properties are unique. In appearance, it often takes a specific form, either crystalline or powdery. However, the appearance of this form is also affected by many factors, such as preparation process and environmental conditions.
When it comes to solubility, it behaves differently in different solvents. In some polar solvents, it may exhibit good solubility because the polar groups contained in the molecular structure, such as hydroxyl groups and sulfonamide groups, can form hydrogen bonds or other interactions with the polar solvent molecules, thereby enhancing its solubility. However, in non-polar solvents, its solubility may be very small, because the molecule as a whole does not fully exhibit non-polar characteristics.
Melting point and boiling point are also key parameters characterizing its physical properties. The melting point of a substance is the temperature corresponding to its transition from solid to liquid state, which reflects the strength of intermolecular forces. If the intermolecular force is strong, the energy required for the molecule to break free from the lattice and become a liquid state will be higher, and the melting point will also increase accordingly; otherwise, the melting point will decrease. The boiling point is also similar, which is the temperature when the substance changes from liquid to gas state, and its level is also closely related to the intermolecular force and molecular structure.
In addition, density is also one of its physical properties. Density reflects the mass of the substance in a unit volume, and its value is related to factors such as the accumulation mode of molecules and the relative molecular mass. Different crystal structures or molecular arrangements will cause differences in density.
Furthermore, the physical properties such as color and odor of the substance cannot be ignored. The appearance of color is related to the chromophores such as the conjugated system existing in the molecular structure. Factors such as the size of the conjugated system and the distribution of electron clouds can all affect the color. In terms of odor, or because of the specific functional groups it contains, it emits a weak odor under specific conditions, but the odor may not be significant and needs to be detectable under specific environmental and sensitive conditions.
From the above perspective, the physical properties of the potassium salt of 1-amino-9,10-dihydro-4- (5- ((2-hydroxyethyl) sulfonamido) -3,4-xylene-amino) -9,10-dioxo-anthracene-2-sulfonate are formed by the joint action of many factors, and each property is interrelated to describe the unique physical appearance of this substance.

The first is based on anthraquinone compounds, which have a conjugated aromatic ring structure and are the basis for the initiation of the reaction. Here, the specific position of anthraquinone can be introduced by nucleophilic substitution. The introduction of this amino group is like a key chess for the subsequent reaction. The reaction conditions need to be carefully controlled. The temperature is related to the reaction rate and product selectivity; the nature of the solvent affects the solubility and reactivity of the reactants; the choice of catalyst accelerates and guides the reaction.
Then, for the structure of 9,10-dihydro-9,10-dioxanthracene, a group containing (5- ((2-hydroxyethyl) aminosulfonyl) -3,4-dimethylanilinyl) is introduced at a specific position. This step should be achieved by acylation or nucleophilic addition. The acylation reaction requires the selection of a suitable acylating reagent, such as acid chloride or acid anhydride, and under alkali catalysis, it binds to the active check point in the anthraquinone derivative. Nucleophilic addition requires the creation of a suitable nucleophilic environment, so that the nucleophilic reagent containing the target group is precisely added to the specific carbon site of anthraquinone.
As for the formation of sulfonates, sulfonating reagents such as concentrated sulfuric acid or chlorosulfonic acid can be introduced into the reaction system. The timing of sulfonation is also critical. Early introduction, or other activity check points are sulfonated, affects the purity of the product; too late introduction, may make the reaction difficult. The sulfonation process requires close monitoring of the reaction process to accurately achieve the target product 1-amino-9,10-dihydro-4- (5- ((2-hydroxyethyl) aminosulfonyl) -3,4-dimethylanilino) -9,10-dioxo-anthracene-2-sulfonate formation. After separation, purification and other steps, the pure product can be obtained.
