The physical properties of 1 - [ (4-ethylbenzoyl) methyl] -1H-indole are as follows:
Appearance properties are often crystalline solid, stable and existing at room temperature and pressure. Its melting point is quite critical, which is the key point for determining the purity and characteristics, but the exact value will vary slightly depending on the impurities involved and the measurement method. Generally speaking, it is mostly in a specific temperature range, which is the critical temperature for the substance to change from solid to liquid.
In addition, its solubility is also an important property. In organic solvents, such as common ethanol, chloroform, dichloromethane, etc., show a certain degree of solubility. In ethanol, depending on the temperature and concentration, it can be partially dissolved to completely dissolved. In polar solvent water, due to the characteristics of molecular structure, the degree of solubility is extremely low, almost insoluble, because most of the molecules are non-polar hydrocarbon structures, and the interaction with water molecules is weak.
In addition, the density of the substance is also an inherent property. Although the exact value needs to be determined by professional instruments, the approximate range reflects its density compared with common substances, which helps to predict its behavior during related operations such as mixing and separation. Its stability in the air cannot be ignored either. Although it is relatively stable at room temperature and pressure, under special environmental conditions such as high temperature, high humidity or strong light irradiation, certain physical changes may occur, such as crystal transformation, which in turn affects its many physical properties.

To prepare 1 - [ (4 - ethoxy benzyl) methyl] - 1H - indole, the method is as follows:
First take 4 - ethoxy benzaldehyde, make it and nitromethane co-placed in the reactor, accompanied by an appropriate amount of catalyst, temperature control in a certain range, so that it undergoes a condensation reaction to obtain 4 - ethoxy - β - nitrostyrene. In this step, attention should be paid to the regulation of temperature. If the temperature is too high or too low, it can cause the deviation of the reaction and affect the yield and purity of the product. < Br > The 4-ethoxy - β - nitrostyrene is moved to another reaction vessel, and a suitable reducing agent, such as metal zinc powder and acetic acid system, is added to slowly react to gradually reduce the nitro group to an amino group to obtain 4-ethoxy phenethylamine. During operation, the amount of reducing agent, reaction time and rate must be carefully controlled to prevent excessive reduction or insufficient reaction. < Br > The prepared 4-ethoxyphenethylamine is then mixed with acetaldehyde in a specific solvent, an acid catalyst is added, and the cyclization reaction is carried out at temperature. After the process of intramolecular cyclization, the final product is 1- [ (4-ethoxybenzyl) methyl] -1H-indole. In this step, the choice of solvent, the type and amount of catalyst have a great influence on the process of the reaction and the structure of the product, and must be optimized by many tests.
After each step of the reaction, the product needs to be purified by suitable separation and purification methods, such as extraction, column chromatography, etc., to remove impurities and improve its purity. Only then can the qualified raw materials be provided for the next reaction or final application.

First talk about its quality. Those who are of high quality, the price will be high; those who are of poor quality, the price will be low. If its craftsmanship is exquisite, the materials used are high-quality, and it is effective in medical or other uses, the price will be high.
Re-discussion of supply and demand. If there are many people who want it in the market, but there are few people who produce it, the so-called "rare is expensive", and its price will rise. On the contrary, if the supply exceeds the demand, the price may drop.
Furthermore, the situation of the world is also relevant. The world is tranquil, and business travel is Tongtai, and its price may be stable; if there is chaos, there will be frequent soldiers, business travel will be blocked, and production and transportation will be difficult. Prices will fluctuate, or rise sharply and unpredictable.
There are all kinds of merchants, and their business skills are different, which also make prices different. There are those who take small profits but quick turnover as a strategy, and the price may be slightly lower; there is a strong brand reputation, win with quality, and set high prices.
However, it is not easy to determine the domain of its price. Roughly speaking, in normal times, if the quality is average, the price may be between a few dollars and a few taels of silver; if the quality is good and the need is met, the price may be dozens of taels of silver. However, the market conditions are ever-changing, and this is only an estimate of the imagination, making it difficult to make an accurate conclusion.
