2-(1-((((3,5-difluorophenyl)amino)carbonyl)hydrazono)ethyl)3-pyridinecarboxylic acid

This question is related to the chemical structure of 2 - (1 - ((3,5 - diethylamino) amino) benzyl) amino) ethyl - 3 - pyridine carboxylic acid. The structure of this compound is quite complex, so let me go into it in detail.
Its core structure is connected by a pyridine ring and a carboxylic acid group, which is a nitrogen-containing hexagonal heterocycle and has aromatic properties. In the third position of the pyridine ring is connected a carboxylic acid group, which gives the compound a certain acidity and can participate in many chemical reactions, such as salt formation reactions, esterification reactions, etc.
Looking at the 2- (1- ((3,5-diethylamino) amino) benzyl) amino) ethyl moiety. "2-ethyl" indicates that there is an ethyl group connected on the main chain, and the ethyl group is a saturated alkyl group, which is relatively stable. And the "1- ((3,5-diethylamino) amino) benzyl) amino" moiety, benzyl is benzyl. The phenyl ring is a stable aromatic structure, which has an important impact on the electron cloud distribution and chemical properties of the whole molecule. Multiple amino groups are connected, and the amino group is alkaline, can react with acids to form salts, and is often an active check point in organic synthesis, which can participate in nucleophilic substitution and other reactions. Diethylamino is the connection of two ethyl groups on the amino group, which changes the electron cloud density and steric resistance of the amino group, and affects the alkalinity of the compound and the interaction with other molecules.
This compound exhibits unique chemical and physical properties due to the interaction of various groups. It may have important application value in organic synthesis, medicinal chemistry and other fields, and can be used as a key intermediate for the synthesis of specific drugs or functional materials.

I look at your words, which seem to be related to chemistry, but the expression is a little complicated and obscure. Try it for you.
Here it is mentioned "2 -% 281 -% 28% 283% 2C5 - Diethylphenyl% 29 Amino% 29 aldehyde% 29 Carboxyl% 29 Isopropyl% 29 - 3 - What are the physical properties of its carboxylic acid".
In this compound, the presence of the carboxyl group gives it a certain acidity. The carboxyl group can participate in the formation of hydrogen bonds, so the compound has a certain solubility in suitable solvents, especially in polar solvents such as water, or has a certain solubility due to the formation of hydrogen bonds between the carboxyl group and water molecules. The presence of the
aldehyde group makes the compound have certain redox properties. The aldehyde group can be oxidized to a carboxyl group or reduced to a hydroxyl group under specific conditions.
The alkyl moiety, such as isopropyl and diethylphenyl, will affect the overall polarity of the compound because it is a non-polar group. The presence of alkyl groups increases the solubility of the compound in non-polar solvents, and due to its relatively large steric resistance, it has an impact on the intermolecular interaction of the compound, which in turn affects its melting boiling point.
Because the carboxyl group can form hydrogen bonds, the intermolecular force is enhanced, and the melting boiling point of this compound should be higher than that of non-polar compounds with similar relative molecular weights. At the same time, molecules contain a variety of functional groups, or they can participate in a variety of chemical reactions, exhibiting rich chemical properties, which are also correlated with physical properties.

The main use of 3- (1- ((3,5 -diethylamino) amino) carbonyl) thio) ethyl) amino-3-pentenoic acid is for the research and development of related drugs in the field of medicinal chemistry. In drug synthesis, it often acts as a key intermediate. With its unique chemical structure, it can react with many other compounds, and then construct complex molecular structures with specific pharmacological activities.
For example, in the development of certain cardiovascular disease therapeutic drugs, this compound can be integrated into the drug molecular structure through specific chemical reactions to give the drug better targeting and biological activity, so as to achieve more precise and effective treatment of cardiovascular diseases. Or in the research and development of some nervous system drugs, it participates in the reaction as an intermediate, which helps to shape the molecular morphology suitable for passing through the blood-brain barrier and improve the therapeutic effect of drugs on nervous system diseases.
Furthermore, in the field of anti-tumor drug research, it may also play an important role. By combining with other anti-tumor active fragments, new anti-tumor drugs may be developed, providing a new way and possibility for conquering tumor diseases. Due to its chemical structure characteristics, it can bring diverse changes and combinations to drug design, so it has value and use that cannot be ignored in the research and development process of modern medicinal chemistry.

To prepare 2 - (1 - ((3,5 - diethylphenyl) amino) benzyl) pyridine) ethyl) - 3 - to its carboxylic acid, the preparation method is as follows:
First take an appropriate amount of 3,5 - diethylbenzene and react it with a suitable reagent containing amino groups to obtain (3,5 - diethylphenyl) amino intermediates. In this step, attention should be paid to the control of reaction conditions, such as temperature, pH, etc., to avoid the growth of side reactions.
Then, the prepared (3,5-diethylphenyl) amino intermediate is mixed with the reactant containing benzyl structure, so that a specific chemical reaction occurs, thereby generating ((3,5-diethylphenyl) amino) benzyl related products. In this process, the choice of solvent is quite critical, and it is necessary to choose those with good compatibility with the reactants and no adverse effect on the reaction.
Furthermore, the above products are reacted with pyridine derivatives, and through a clever reaction path, 2 - (1 - ((3,5-diethylphenyl) amino) benzyl) pyridine) ethyl related substances are obtained. In this reaction step, the choice of catalyst is very important, and the one that can effectively improve the reaction rate and yield needs to be selected according to the reaction characteristics.
Finally, for the generated 2 - (1 - ((3,5 - diethylphenyl) amino) benzyl) pyridine) ethyl product, the 3-carboxylic acid structure is introduced by suitable chemical means, and the final product is 2 - (1 - (((3,5 - diethylphenyl) amino) benzyl) pyridine) ethyl) -3 -carboxylic acid. In this process, the monitoring of the reaction process is indispensable. Analytical methods such as thin-layer chromatography can be used to precisely control the progress of the reaction to ensure the purity and yield of the product. After each step of the reaction, proper separation and purification operations are required, such as recrystallization, column chromatography, etc., to remove impurities and improve product quality.

I look at what you are asking, and it seems to involve the domain of drug names and market prices. However, the words described are obscure and difficult to understand, and there are many symbols and chaos. For example, the combination of characters such as "2-%281-%28%28%283%2C5-%E4%BA%8C%E6%B0%9F%E8%8B%AF%E5%9F%BA%29%E6%B0%A8%E5%9F%BA%29%E7%BE%B0%E5%9F%BA%29%E8%82%BC%E5%8F%89%29%E4%B9%99%E5%9F%BA%29-3-" is not easy for me to understand.
If it is common sense, the market price of "3,5-divinylbenzene" is often different due to quality, purity, and supply and demand trends. However, without accurate information, it is difficult to determine its price range.
As for other groups, such as those mentioned, it is difficult to clarify their exact meaning due to the clutter of expressions, let alone talk about the price range related to them.
May you restate this question in clearer and more formal terms, so that I can examine it in detail and clarify your doubts.
