To prepare 1-4- (4-fluorophenyl) -6-fluoro-7-chloro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid, there are many methods. Although the chemical book "Tiangong Kaiwu" in the past did not describe this thing in detail, the method of synthesis can be deduced by referring to the theory of its creation.
One method can be started by a suitable fluorobenzene derivative. First, the fluorobenzene and a specific halogen are reacted with nucleophilic substitution under appropriate catalysts and reaction conditions to construct the connection between the benzene ring and other structural fragments. In this regard, the choice of catalyst is crucial, and its activity, selectivity and adaptability to the reaction conditions need to be considered.
Next, the group containing chlorine and fluorine is introduced at the appropriate position. Or it can be achieved by halogenation reaction, and the temperature, time and proportion of the reactants can be precisely controlled, so that the chlorine and fluorine atoms can be connected to the molecule at the desired position. This step requires fine regulation, because the selectivity of the halogenation reaction is easily affected by many factors.
After a series of cyclization reactions, the structure of the quinoline ring is constructed. This process may require a specific dehydrating agent or shrinking agent to promote the formation of intra-molecular rings. The control of reaction conditions depends on the efficiency of cyclization and the purity of the product.
Then, the obtained product is oxidized to convert the group at a specific position into a carbonyl group to obtain a 4-oxo-substituted structure. The selection of oxidation reagents, the acidity and alkalinity of the reaction medium, etc. are all key factors affecting the reaction.
Finally, carboxyl groups are introduced. It can be achieved by hydrolysis, carboxylation, etc. According to different reaction paths, suitable reagents and conditions are selected, so that 1-4- (4-fluorophenyl) -6-fluoro-7-chloro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid is finally obtained. The whole process of synthesis requires careful study of each step in order to achieve efficient and pure synthesis.

This substance is 1-4% (4-fluorophenyl) -6-fluoro-7-chloro-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid, and its physical and chemical properties are as follows:
In appearance, it is mostly white to light yellow crystalline powder, with pure color and no obvious variegation and foreign matter. In terms of solubility, the substance is slightly soluble in water, and it is difficult to dissolve and disperse in large quantities in water. This is due to the characteristics of its molecular structure, which makes its interaction with water molecules weak. However, it is soluble in some organic solvents, such as the common dimethyl sulfoxide (DMSO), and can be dispersed more uniformly in DMSO to form a uniform solution system, which provides convenient conditions for its application in some chemical experiments and reactions.
Its melting point is usually in a specific temperature range, which is one of the important physical markers of the substance. By accurately measuring the melting point, its purity can be determined. If the purity of the substance is high, the melting point range is relatively narrow and close to the theoretical melting point value; if there are impurities, the melting point may be offset and the melting range may be widened.
In terms of chemical stability, the substance has a certain stability in conventional temperature and humidity environments, but in extreme chemical environments such as strong acids and bases, its chemical structure may change. For example, in strong acid media, some chemical bonds in its molecules may break or rearrange, resulting in chemical properties transformation, which in turn affects its application as a raw material or intermediate in related chemical synthesis.

I look at what you said "1 - 4% 28 4 + - + FLUOROPHEN YL% 29 - 6 + - + FLUORO - 7 + - + CHLORO - 1% 2C 4 + - + DI HYDRO - 4 + - + OXO - QUINOLINEChemicalbook - 3 + - + CARBOXYLIC", which is a complex chemical expression. However, it is not easy to know its price in the market.
Remembering the book "Tiangong Kaiwu" in the past, which recorded all kinds of process products in detail, but the chemical products at that time were not as complicated as they are today. Today, in order to know the price of this chemical, it is necessary to look at many factors such as the state of market supply and demand, the difficulty of production, the price of raw materials, etc.
Or in a chemical specialized city, ask the merchant to get the approximate price. Or in chemical-related books and newspapers, find the records of past transactions to deduce the price range. There are also chemical trading platforms, which may have the price of this chemical.
However, it is difficult for me to determine the exact price, because the market is changing rapidly, and the price fluctuates accordingly. To get an accurate price, you need to explore the market in person and study all kinds of relevant information in detail.
