2-(Trifluoromethyl)-1,3-Benzothiazole

"Tiangong Kaiwu" says: "The main use of di (triethyl) -1,tri-naphthalene anthraquinone is particularly important. The two have different uses.
Triethyl is mostly used in the field of organic synthesis. In the preparation of fine chemicals, it is often a key raw material. Because of its special chemical structure, it can participate in many complex chemical reactions. Through ingenious synthesis paths, a variety of compounds with special properties can be prepared. For example, in the synthesis of pharmaceutical intermediates, it plays an important role in helping to create new drugs and contributing to human health.
And tri-naphthalene anthraquinone is mainly used in the field of materials science. It has excellent performance in the preparation of optoelectronic device materials. Due to its unique optical and electrical properties, when applied to organic Light Emitting Diode (OLED), solar cells and other devices, the performance of the device can be significantly improved. Such as enhancing the luminous efficiency of OLEDs, improving the photoelectric conversion efficiency of solar cells, and injecting strong impetus into the development of new optoelectronic devices.
Although both are important chemical substances, due to their differences in structure and performance, they shine in different scientific and technological fields and contribute to industrial progress and scientific development.

To prepare 2 - (triethylmethyl) -1,3 - anthracylimidazolone, the synthesis method is as follows:
The first method is to use anthraquinone as the starting material. Anthraquinone can be nitrified to obtain 1 - nitroanthraquinone. This step needs to be carried out in a mixed acid system composed of sulfuric acid and nitric acid, and the temperature should be controlled in a specific range to prevent excessive nitrification. 1 - Nitroanthraquinone can be converted into 1 - Aminoanthraquinone after reduction. Commonly used reducing agents include iron powder and hydrochloric acid.
After obtaining 1 - amino anthraquinone, it is reacted with glyoxal and methylamine in a suitable solvent. This step is a condensation reaction. The reaction conditions are very critical, such as temperature and pH value, which need to be carefully regulated to make the reaction proceed smoothly towards the direction of generating the target product 2 - (triethylmethyl) -1,3 - anthracylimidazolone.
Another way is to use 1-chloroanthraquinone as the starting material. 1-chloroanthraquinone first reacts with methylamine to achieve amination to obtain 1-methylaminoanthraquinone. Then, 1-methylaminoanthraquinone and glyoxal are condensed under specific conditions to obtain the target product. In this route, the choice of solvent and catalyst for each step of the reaction will affect the yield and purity of the reaction.
There are also those who use anthracene as the starting material. Anthracene is oxidized to obtain anthraquinone first, and the subsequent steps are similar to the method using anthraquinone as the starting material. However, the oxidation reaction of anthracene needs to select suitable oxidants and reaction conditions to ensure the yield and quality of anthraquinone.
All these synthesis methods have their own advantages and disadvantages. The method using anthraquinone as the starting material has a relatively mature route, but the raw material cost may be higher; the method using 1-chloroanthraquinone as the starting material, some reaction conditions may be easier to control, but the toxicity and environmental impact of chlorine compounds need to be concerned; for anthracene as the starting material, although the raw material is cheap, the early oxidation steps may be more complicated. In actual synthesis, when considering factors such as specific demand, availability of raw materials and cost, the optimal method is selected.

"Tiangong Kaiwu" says: "Of the triethyl group, di- (triethyl) -1,3-naphthalene and anthraquinone, this is an organic compound. Its physical properties can be investigated.
Watching this thing, at room temperature, is mostly in the shape of a solid state. Its color is dark or light, often dull, or brown, or nearly black brown. As for its smell, it has a slightly peculiar taste, but it is not a pungent and intolerable genus.
As far as its melting point is concerned, the melting point is quite high, and it needs a considerable amount of heat to melt it; the boiling point is not low, and it needs to be extremely hot to make it boil and vaporize. And the solubility of this substance in water is not good, and it is difficult to dissolve with water. Because of its molecular structure, it has strong hydrophobicity. However, it is soluble in some organic solvents, such as aromatic hydrocarbons and halogenated hydrocarbon solvents.
Furthermore, the density of this substance is greater than that of water. If placed in water, it will sink to the bottom of the water. Its texture is slightly brittle and hard, and when ground, it is easy to form a powder. Under light, it is slightly shiny, but it is not as dazzling as a metal, but it is the unique luster of organic matter. These are the physical properties of di- (triethyl) -1,3-naphthalene and anthraquinone.

2-%28%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%29-1, that is, 2 - (trichloromethyl) -1,3 - naphthalene anthraquinone compounds, its chemical properties are relatively stable.
From the structure point of view, trichloromethyl has a certain electron absorption, which will affect the electron cloud distribution of the whole molecule, and then affect its chemical activity. The structure of naphthalene anthraquinone itself has a certain conjugate system, which endows the compound with a certain stability. The conjugate system can delocalize the electrons and reduce the energy of the molecule, thereby enhancing the stability of the compound.
Under common chemical reaction conditions, the compound is not prone to spontaneous decomposition or rearrangement and other reactions. However, its stability is not absolute, and reactions may still occur under extreme conditions such as specific strong oxidants, high temperatures, high pressures, and the presence of catalysts. For example, strong oxidants may attack the conjugated system of naphthalene anthraquinone, or react with trichloromethyl, resulting in structural changes. However, in general environments and conventional chemical operations, 2- (trichloromethyl) -1,3-naphthalene anthraquinone can maintain relatively stable chemical properties, making it potentially valuable in some application scenarios that require stable chemical structures.

"Tiangong Kaiwu" has a saying: "The silk, hemp, fur, and brown in the world all have qualities, so that the special face can still be seen. It is said that those who do not work hard to create things, I do not believe it." Today, I am inquiring about the price of 3-benzimidazoline in the city, and its price range is quite popular.
However, I do not know the current market conditions of this product. The price of building a market often varies due to factors such as time, place, supply and demand. If you want to know its exact value, you can only know the recent selling price when you consult the people of pharmaceutical companies, the market of chemical materials, or the relevant business information platforms.
Or the price varies depending on the quality of the material and the manufacturer. The price of the refined one may be high, and the price of the crude one may be low. And if the supply and demand are strong at times, the price may rise; when the supply and demand are weak, the price may be depressed. It is difficult to determine the exact price.
To obtain the exact price of 3-benzimidazoline in the market, it is necessary to search for the current market information in order to obtain a near-real price range.
