(2Z) -3- (dicyanomethylene) 2- {[4- (dihexylamino) -2-methylphenyl] methylene} -2,3-dihydro-1H -1-benzothiophene-1,1-diol salt, the physical properties of this compound are as follows:

Looking at its morphology, it often shows a specific crystalline appearance, and the specific crystal structure is determined by the interaction and arrangement of molecules. Its color may be colorless to microstrip color, depending on the synthesis conditions and purity.

When it comes to the melting point, at a specific temperature, the substance changes from solid to liquid state. This melting point temperature is one of its important physical characteristics, which can help to distinguish the purity and identify the substance. However, the exact melting point value needs to be determined by precise experiments, and may vary slightly due to different experimental environments and equipment.

In terms of solubility, it varies in organic solvents. In some common organic solvents, such as halogenated hydrocarbon solvents such as dichloromethane and chloroform, it may have certain solubility, which can enhance the interaction with such organic solvents due to the lipophilic long-chain alkyl groups in the molecular structure. However, in solvents with strong polarity, such as water, their solubility may be poor, and it is difficult to form an effective solvation due to the large difference in the polarity of the whole molecule and the polarity of water.

The density of this compound is also an important physical property, and its value reflects the degree of tight accumulation of molecules and mass distribution. However, accurate density data also need to be measured experimentally. And the density is affected by temperature, usually the temperature increases, the density decreases slightly, and the molecular thermal motion intensifies due to temperature, and the molecular spacing increases slightly.

In addition, its refractive index is also of characterization significance. The refractive index is related to the influence of molecules on light propagation, reflecting the optical properties of substances, and can assist in the identification and purity analysis of substances. However, the exact value needs to be determined by professional instruments.

The synthesis method of (2Z) -3- (dicyanomethylene) 2- {[4- (dihexylamino) -2-methylphenyl] methylene} -2,3-dihydro-1H -1-benzothiophene-1,1-diol salt can be as follows.

First, prepare all kinds of raw materials, the required things are 4- (dihexylamino) -2-methylbenzaldehyde, 3- (dicyanomethylene) -2,3-dihydro-1H -1-benzothiophene-1,1-diol, etc., and need to prepare suitable solvents and catalysts, such as commonly used organic solvents ethanol or dichloromethane, and piperidine with catalytic effect.

Then, in a clean and dry reaction vessel, in a certain ratio, 4- (dihexylamino) -2-methylbenzaldehyde and 3- (dicyanomethylene) -2,3-dihydro-1H -1-benzothiophene-1,1-diol are added, and then an appropriate amount of prepared solvent is added, so that the reactants can be uniformly dispersed. Subsequently, carefully add the catalyst piperidine, the amount of this catalyst needs to be precisely controlled, the reaction will be too fast, and the catalytic effect will be poor at least.

Next, the reaction vessel is placed under suitable temperature conditions for reaction. Generally speaking, the temperature is controlled at 50-80 ° C. In this temperature range, the reactants interact, and many reaction steps such as rearrangement and addition occur between molecules. During the reaction, it is necessary to continuously stir with a stirring device to make all parts of the reaction system fully contact and promote the uniform progress of the reaction.

After the reaction continues for a period of time, after confirming that the reaction has reached the expected level by thin layer chromatography or other suitable monitoring means, the reaction is terminated. After that, the reaction products are separated and purified. The method of reduced pressure distillation can be used to remove the solvent in the reaction system, and then the method of column chromatography can be used to select a suitable eluent to separate the target product from the impurities, and finally obtain a pure (2Z) -3- (dicyanomethylene) 2- {[4- (dihexylamino) -2-methylphenyl] methylene} -2,3-dihydro-1H-1-benzothiophene-1,1-diol salt.

The first to bear the brunt is its molecular structure. Looking at its structure, there is a conjugate system in it, which usually increases the stability of molecules. Like conjugate double bonds, the electron cloud can be delocalized, which reduces the molecular energy and improves the stability. The aromatic ring structure in this compound is also helpful for the stability. The aromatic ring has a special electron cloud distribution and resonance structure, which can enhance the overall stability of the molecule.

However, there are also groups in the compound that may affect the stability. For example, the dicyanomethylene and diol salt parts, the cyanyl group has strong electron absorption, or changes the density of the surrounding electron cloud, which affects the molecular stability; the oxygen atom in the diol salt part, the electron cloud distribution and bond energy status are also closely related to the stability. In case of external environmental changes, such as temperature increase, molecular thermal motion intensifies, chemical bond vibration increases, or bond energy decreases, causing molecular decomposition or rearrangement, and stability is damaged. < Br >
Re-examine the chemical environment. If the compound is in an acid-base environment, it may react with acid and base due to the characteristics of some groups in its structure. For example, the diol part is in an acidic environment, or a protonation reaction occurs, which changes the molecular structure and charge distribution, which in turn affects the stability.

There is also a solvent factor, and different solvents have different solubility and interaction with the compound. Polar solvents may interact with the polar part of the compound, affecting the intermolecular force and changing the stability.

First, purity has a great impact. High purity, due to the difficulty of preparation and complex purification process, the price is often high; low purity, preparation is relatively simple, the price is slightly lower.

Second, the supply and demand relationship is the key factor. If the market demand is strong and the supply is scarce, the price will rise; if the demand is low and the supply is sufficient, the price may fall.

Third, the preparation cost cannot be ignored. The cost of raw materials, the number of synthesis steps, and equipment requirements will all have an impact on the final price. Rare and expensive raw materials, or cumbersome synthesis steps, the cost will be high, and the price will also increase.

Fourth, the sales region and channel also have an impact. The price level varies in different regions, and the difference in sales channels will also make the price different.

Due to the lack of more market data, it is difficult to give the exact price range. For more information, please consult a professional chemical reagent supplier or check on the relevant chemical product trading platform to obtain more accurate price information.
