What are the physical properties of the'Benzenesulfonicacid, 2- [ (10-Dihydro-4-Hydroxy-9, 10-Dioxo-1-Anthracenyl) Amino] -5-Methyl-, Monosodium Salt (9Ci) 'product
This substance is 2 - [ (9,10 - dihydro - 4 - hydroxy - 9,10 - dioxo - 1 - anthracyl) amino] -5 - monosodium methylbenzenesulfonate (9Ci). Its physical properties are as follows:
In terms of concept, it is either a solid state, often in powder or crystalline form, because many organic sulfonate compounds have this form. In terms of color, anthraquinones have many such color characteristics in view of the existence of anthraquinone structures, or their color is between yellow and orange.
In terms of solubility, as a sodium salt, it may have certain solubility in water. Sodium ions can interact with water molecules to form hydrated ions, causing the substance to dissolve in water. However, in organic solvents, the solubility may be different, depending on the polarity of the organic solvent. In polar organic solvents, there may be a certain solubility; in non-polar organic solvents, the solubility may be extremely low.
Melting point is also an important physical property, but the exact melting point needs to be accurately determined experimentally. It is speculated that its melting point may be higher. Due to the presence of conjugated systems and ionic bonds in the molecule, the intermolecular force is enhanced, and higher energy is required to melt it.
In terms of stability, under conventional conditions, if properly stored, it should have certain stability. When encountering specific chemicals such as strong oxidants, strong acids or strong bases, it may react chemically. Because of its hydroxyl, sulfonic acid and anthraquinone structures, these groups all have certain reactivity. For example, hydroxyl groups can be oxidized, and sulfonic acid groups can neutralize with bases. Environmental factors such as light and high temperature may also affect their stability and accelerate their decomposition or deterioration.

To prepare "Benzenesulfonic acid, 2- [ (9,10 - Dihydro - 4 - Hydroxy - 9,10 - Dioxo - 1 - Anthracenyl) Amino] -5 - Methyl -, Monosodium Salt (9Ci) " The method is as follows:
Take anthraquinones first, because they have the key 9,10 - dihydro - 9,10 - dioxo - 1 - anthracene group structure. Under appropriate reaction conditions, the hydroxyl group is introduced at the 4 - position of the parent anthraquinone, which can be achieved by specific nucleophilic substitution or oxidation reactions. A suitable hydroxylation reagent can be selected, such as an oxygenated reagent with specific activity, and with the assistance of a catalyst, it can be precisely formed into a hydroxyl group at the target position.
Then take the methyl-containing benzenesulfonic acid derivative and connect it to the hydroxylated anthraquinone product. This linking reaction may be a nucleophilic substitution path, and the activity check point of the benzenesulfonic acid derivative interacts with the amino active end of the anthraquinone. During the reaction, it is necessary to adjust the reaction temperature, solvent environment and the proportion of reactants to make the two efficiently combine, and connect to the [ (9,10-dihydro-4-hydroxy-9,10-dioxo-1-anthracene) amino] structure at the 2-position of benzenesulfonic acid, and retain the methyl group at the 5-position.
After the final product is obtained, an appropriate amount of basic sodium source is used to react with it, so that the benzenesulfonic acid group is converted into a monosodium salt form. The neutralization salt-forming reaction should be carried out under mild conditions, and the amount of sodium source should be precisely controlled to ensure that only monosodium salts are generated without the risk of overreaction, so that "Benzenesulfonic acid, 2- [ (9,10 - Dihydro - 4 - Hydroxy - 9,10 - Dioxo - 1 - Anthracenyl) Amino] -5 - Methyl -, Monosodium Salt (9Ci) " can be obtained. Each step of the reaction needs to be carefully tested to achieve the desired output and purity.
