1-Ethoxy-2,3-difluoro-4 - [ [( trans, trans) -4 '-ethyl [1,1' -bicyclohexyl] -4-yl] methoxy] benzene, in the field of industrial creation, is often the key component of liquid crystal materials.
Liquid crystal is a substance with a special phase state, which has both liquid fluidity and crystal optical anisotropy. In liquid crystal materials, this compound can significantly affect the physical properties of liquid crystals by virtue of its specific molecular structure. Its structural parts such as ethoxy, difluorine atoms and bicyclohexyl methoxy work together to have an important impact on the stability of the liquid crystal phase, the phase transition temperature range and optical properties.
With the rapid development of display technology, liquid crystal displays (LCDs) are widely used in many electronic devices, such as TVs, computer displays, mobile phone screens, etc. This compound is used in LCDs to help the liquid crystal molecules to achieve an orderly arrangement, achieve precise control of the direction of light propagation, and then present a clear image. Due to the suitable phase transition temperature, the liquid crystal can maintain a stable phase state at common ambient temperatures, ensuring the reliability and stability of the display effect. Its unique optical properties also help to enhance the contrast and color saturation of the display, making the image more vivid and realistic.

1-Ethoxy-2,3-difluoro-4 - [ [( trans, trans) - 4 '-ethyl [1,1' -bicyclohexyl] -4-yl] methoxy] benzene, the physical properties of this substance are as follows:
Looking at its properties, under normal temperature and pressure, it is mostly a clear and transparent liquid. Its fluidity is quite good, just like the water of a stream, smooth and no stagnation. This is because the intermolecular forces are in a specific range, which makes it have such flow characteristics.
When it comes to the melting point, the melting point of this compound is in a relatively low range. Although there is a certain rigid structure in the molecular structure, such as the bicyclohexyl part, the existence of flexible groups such as ethoxy and methoxy weakens the degree of close arrangement between molecules, so the melting point is limited and cannot be at a high level.
Boiling point also has its own unique features. The comprehensive effect of intermolecular forces, including van der Waals forces and possible weak hydrogen bonds, jointly determines its boiling point. Due to the interaction of the groups in its structure, the energy required for the molecule to break away from the liquid phase is at a specific value, which corresponds to a specific boiling point.
Solubility is also one of the important physical properties. In organic solvent systems, such as common toluene and dichloromethane, this substance exhibits good solubility. This is due to the fact that there is a similar interaction pattern between its molecular structure and the molecules of organic solvents, which is in line with the principle of "similar miscibility". Van der Waals forces can be formed between parts such as benzene rings and fluorine atoms and organic solvent molecules, which promotes their uniform dispersion in organic solvents.
In terms of density, it is within a certain range compared with common organic solvents. The relative mass of its molecules and the degree of molecular packing compactness work together to form this specific density value.
In terms of optical properties, due to the conjugated structure in its molecules, such as the benzene ring system, it may exhibit certain absorption characteristics under specific wavelengths of light, which may have unique performance in the field of spectroscopy research.

1-Ethoxy-2,3-difluoro-4 - [ [ ( trans, trans) - 4 '-ethyl [1,1' -bicyclohexyl] -4-yl] methoxy] benzene, this compound has many chemical properties. In terms of physical properties, it is mostly colorless and transparent to slightly yellow clear liquid under normal circumstances, similar to many benzene derivatives, and has certain fluidity. Its boiling point and melting point are affected by intermolecular forces. The structure of benzene ring and bicyclohexyl in the molecule makes the intermolecular forces more complicated, resulting in a relatively high boiling point. Under heating conditions, it needs to reach a certain temperature to boil into a gaseous state; the melting point determines the temperature at which it changes from a solid state to a liquid state.
Chemically, the ethoxy group in this compound is relatively active and can participate in nucleophilic substitution reactions. The oxygen atom in the ethoxy group is rich in lone pair electrons, which can be used as a nucleophilic agent to attack suitable substrates, such as reacting with halogenated hydrocarbons to achieve the transfer of ethoxy groups. The fluorine atom on the benzene ring will affect the electron cloud distribution of the benzene ring due to its large electronegativity, which will reduce the density of the electron cloud of the benzene ring. In the electrophilic substitution reaction, the reactivity is different from that of the traditional benzene ring, and it is more inclined to meta-substitution. Although the bicyclohexyl group is relatively stable, under extreme conditions such as strong oxidizing agent or high temperature and high pressure, the ring structure may be destroyed, and reactions such as ring opening may occur. In addition, when the methoxy group is connected to the benzene ring, it will produce electron conjugation effect on the benzene ring electron cloud, enhance the electron cloud density of the benzene ring, and affect the reaction check point and reactivity on the benzene ring. These properties comprehensively determine that the compound has potential application value

The preparation method of 1-ethoxy-2,3-difluoro-4 - [ [ ( trans, trans) - 4 '-ethyl [1,1' -bicyclohexyl] -4-yl] methoxy] benzene is a key matter in the field of chemical synthesis. The preparation method can be obtained from the starting material by multi-step reaction.
First, select a suitable benzene derivative as the starting material. This derivative needs to contain an ethoxy group, a difluoro atom, and an activity check point that can be introduced into the cyclohexyl fragment. The ethoxy group is introduced by a nucleophilic substitution reaction. In this reaction, an appropriate alkoxide is selected to react with the benzene derivative. Under suitable reaction conditions, such as specific temperatures and solvents, the ethoxy group is successfully attached to the benzene ring.
Secondly, difluorine atoms are introduced. Fluorine-containing reagents, such as nucleophilic fluorination reagents, can be used to connect fluorine atoms to specific positions in the benzene ring through nucleophilic substitution or addition reactions. This step requires fine regulation of the reaction conditions, because the introduction of fluorine atoms has a significant impact on the reaction selectivity and yield.
Furthermore, the fragment containing trans-4 '-ethyl [1,1' -bicyclohexyl] -4-yl is prepared and linked to the benzene derivative containing ethoxy and difluoro atoms through appropriate reactions. This linking reaction often involves the formation of carbon-carbon bonds or carbon-oxygen bonds, such as nucleophilic substitution reactions, to form the methoxy linking part of the final target product.
Throughout the preparation process, each step of the reaction requires precise control of the reaction conditions, including temperature, pressure, reaction time, and the proportion of reactants. At the same time, each step of the product needs to be separated and purified to ensure the purity and quality of the final product. Thus, in order to effectively synthesize 1 - ethoxy - 2,3 - difluoro - 4 - [ [ ( trans, trans) - 4 '- ethyl [1,1' - bicyclohexyl] - 4 - group] methoxy] benzene.

Today, there are 1-ethoxy-2,3-difluoro-4- [ (anti, anti) -4 '-ethyl [1,1' -dicyclohexyl] -4-yl] methoxy] benzene. The price range in the market is difficult to determine. The price of various materials in the market often changes over time and is also controlled by many factors.
If the quality of the material, the price of the refined one must be higher than the coarse one. If the benzene has extremely high purity and no impurities, the price may be high; if it contains more impurities and is of inferior quality, the price should be low.
Furthermore, the supply and demand are also heavy. If there are many applicants, but there are few suppliers, the price will rise; if the supply exceeds the demand, the price will be suppressed. The place of origin is near and far, and the manufacturing cost is also related to the price. If it is shipped from a distance, it will cost more to travel, and the price will increase; if the cost of manufacturing is high, the price will also be difficult to lower.
I have checked the records of past transactions, but I have not seen any specific record of the price of this product. If the degree of chemicals like this is used, the price may be between a few yuan and a few hundred yuan per gram. This is only an idea. The actual price must be asked by the chemical material supplier, or it must be carefully checked in the market.
