2-% (1,3-azine-2-yl) -1H-indolo [de] isoquinoline-1,3 (2H) -dione, which has many unique chemical properties. In its structure, indolo [de] isoquinoline is connected to the azine structure, giving it special reactivity.
From the perspective of nucleophilic reactions, the nitrogen atoms in this compound are rich in electrons and are vulnerable to attack by nucleophilic reagents. For example, in an alkaline environment, nitrogen atoms can be replaced by some nucleophilic reagents to generate new derivatives. This process is like "new customers come to the door and replace the old one". Due to its compact structure and special distribution of electron clouds, the reaction is highly selective, just like precise guidance, only acting on specific locations.
When it comes to electrophilic reactions, the electron cloud density in some regions of the molecule is low, which can act as a check point for electrophilic reactions. For example, under suitable conditions, specific electrophilic reagents can attack it and achieve functionalization, which is like adding a "new decoration" to the compound. This process is highly dependent on the reaction conditions and the activity of the electrophilic reagents. When the conditions are suitable, the reaction is efficient and the product purity is good.
In addition, the conjugate structure of the compound gives it unique optical properties. Under photoexcitation, electrons transition in the conjugated system, presenting a fluorescence phenomenon, like a twinkling star in the dark night. This fluorescence property is of great significance in the field of materials science, and may be used to prepare fluorescent probes, just like installing "fluorescence navigation" for the microscopic world, assisting biological imaging and chemical sensing research.
In terms of stability, due to the formation of many conjugates and hydrogen bonds in the molecule, the structure is relatively stable, just like building a strong house, which is not easy to decompose under normal conditions. However, in extreme environments such as strong acids, strong bases, or high temperatures, chemical bonds will also be affected, and they will break or rearrange.

To prepare 2 - (1,3 -thiazole-2-yl) -1H-indole-1,3 (2H) -dione, the following ancient method can be used.
First, appropriate raw materials are taken, and the starting materials of the parent structure of 1,3-thiazole-2-yl related compounds and 1H-indole-1,3 (2H) -dione are necessary. In the reaction system, suitable solvents can be selected, such as organic solvents dimethyl sulfoxide (DMSO) or N, N-dimethylformamide (DMF), etc. These solvents have good solubility to the reaction substrate and can stabilize the reaction environment. < Br >
Then, add an appropriate amount of catalyst. Organic base catalysts, such as triethylamine, can be used, which can effectively promote the progress of the reaction, adjust the pH of the reaction system, and make the reaction move in the direction of generating the target product. The reaction temperature should be controlled within a certain range, and mild heating is appropriate, generally between 50 ° C and 80 ° C. If the temperature is too high, it is easy to cause side reactions to occur and reduce the purity of the product; if the temperature is too low, the reaction rate will be slow and the time-consuming will be too long.
During the reaction process, close attention should be paid to the reaction process. The method of thin layer chromatography (TLC) can be used to regularly monitor the consumption of reaction raw materials and the formation of products. When the raw materials are exhausted or the amount of product generated reaches the expected level, the reaction can be terminated.
After the reaction is terminated, the reaction mixture is post-treated. By extraction, the target product is transferred to the organic phase by using an organic solvent that is incompatible with the reaction system, such as ethyl acetate, etc. After that, the water in the organic phase is removed with a desiccant such as anhydrous sodium sulfate, and the desiccant is filtered to remove the desiccant. The organic solvent is removed by distillation under reduced pressure to obtain a crude product.
Finally, the crude product is purified. The method of column chromatography can be used, and suitable silica gel column and eluent, such as the mixed solvent of petroleum ether and ethyl acetate, can be used as eluent. According to the difference between the adsorption and elution of the product and impurities on the silica gel column, the purification of the product can be realized, and the final product is pure 2- (1,3-thiazole-2-yl) -1H-indole-1,3 (2H) -dione.

I look at what you said about "2- (1,3-naphthidin-2-yl) -1H-benzo [de] isoquinoline-1,3 (2H) -dione", which is a very special chemical substance. However, its price is difficult to determine above the market. The price is influenced by many factors, the first being the difficulty of preparation. The structure of this compound is exquisite and complex, and it needs to go through many difficult processes to prepare. The raw materials are rare and the reaction conditions are harsh, and the preparation cost is high, which necessarily makes it expensive.
Second, the amount of market demand is also the key. If there is strong demand for it in specific fields such as pharmaceutical research and development, materials science, etc., but the supply is limited, the price will rise; conversely, if there is little demand, the price may drop slightly.
Furthermore, the scale of production also affects the price. Large-scale production can reduce the unit cost by means of scale effect, so that the price can stabilize or drop; if only small-scale trial production, the cost is difficult to drop, and the price will rise.
And different suppliers have different pricing due to differences in technology, cost control, etc. From the perspective of "Tiangong Kaiwu", everything has its own method of generation and value tradeoff. Although this chemical substance is not produced by traditional techniques, the formation of its price is also restricted by many factors such as raw materials, craftsmanship, supply and demand as mentioned in the book. Therefore, in order to know the exact market price, it is necessary to check the chemical product trading market in detail, consult professional suppliers, and comprehensively consider all factors to obtain a more accurate price.
