What are the physical and chemical properties of 1- (3-carboxyl-4-fluorobenzyl) -1,4-dihydrophthalazine-4-one?

1 - (3 - carboxyl - 4 - hydroxyphenyl) - 1,4 - diaminoanthraquinone - 4 - sulfonic acid is an organic compound with the following physical and chemical properties:
###traits
At room temperature, it is mostly in solid form, and the color is often yellow to orange-red powder or crystalline. This color is derived from the specific conjugated structure of the molecule, which has unique properties for light absorption.
###solubility
In water, its solubility is limited. Because the molecule contains polar group carboxyl group, sulfonic acid group, and has a large conjugated aromatic ring structure, its solubility in polar solvents is not good. However, in some organic solvents such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), there is a certain solubility, because these organic solvents can form intermolecular interactions with compounds to help them disperse and dissolve.
##Acidic and basic
Intramolecular carboxyl groups and sulfonic acid groups are acidic groups, which can ionize hydrogen ions in aqueous solutions, making the solution acidic. This acidic nature affects the existence and properties of compounds under different pH environments. Under basic conditions, carboxyl groups and sulfonic acid groups easily form salt compounds with metal ions.
###Stability
Under normal storage and use conditions, the compound has good stability. However, in case of strong oxidants, strong acids, strong bases, or extreme conditions such as high temperature and light, its structure will be affected to cause decomposition or chemical reactions. For example, under high temperature, the sulfonic acid group may undergo desulfonation reaction; under the action of strong oxidants, the structural part of anthraquinone will be oxidized, changing the properties of the compound.
##Spectral properties
Because of its conjugated system, it has a characteristic absorption peak in the ultraviolet-visible spectral region, which can be used for qualitative and quantitative analysis. By measuring the absorbance at a specific wavelength, the concentration of the compound can be determined. At the same time, in the infrared spectrum, different functional groups have corresponding characteristic absorption peaks, which can be used for structure identification. For example, carboxyl groups, sulfonic acid groups, amino groups and other functional groups have unique infrared absorption frequencies.

What is the market price of 1- (3-carboxyl-4-fluorobenzyl) -1,4-dihydrophthalazine-4-one?

1-%283-%E7%BE%A7%E5%9F%BA-4-%E6%B0%9F%E8%8B%84%E5%9F%BA%29-1%2C4-%E4%BA%8C%E6%B0%A2%E9%85%9E%E5%97%AA-4-%E9%85%AE%E5%9C%A8%E5%B8%82%E5%9C%BA%E4%B8%8A%E7%9A%84%E4%BB%B7%E6%A0%BC%E5%A6%82%E4%BD%95%3F%2C this is a question about the price of complex chemical substances, but the chemical formulas and other forms in the expression are not standardized, and it is difficult to know the specific substances exactly. If the answer is based on the ancient classical literary style of "Tiangong Kaiwu", it is roughly as follows:

There is a thing today whose name is ambiguous, which seems to be a chemical genus, composed of several groups. Want to know its value in the market. However, the name involves something that is not well known to me. If we extrapolate from common sense, the price in the market often changes for many reasons, such as the distance of origin, the situation of supply and demand, and the difficulty of preparation. If the preparation of such chemical substances is complicated, the raw materials are rare, the origin is remote, and there are many people who need them, the price will be high; if the preparation is simple, the raw materials are widely distributed, and the supply exceeds the demand, the price may be low. However, because the name is difficult to understand, it is difficult to determine its price. Or you need to find someone who is skilled in chemistry and familiar with the market, and study the exact name and characteristics of this object in detail, in order to obtain its fair price in the market.
