Generally speaking, the melting point is about [X] ° C, and the boiling point is about [X] ° C. This property is convenient for its separation and purification under specific temperature conditions.
The compound is insoluble in water, because water is a solvent with strong polarity, and 1- (2-cyanopyridine) -1H-pyrrole-2-ethyl acetate has limited polarity. According to the principle of "similar miscibility", it is insoluble in water. However, it is soluble in common organic solvents, such as ethanol, ether, chloroform, etc. These organic solvents are similar in polarity to the compound and can form intermolecular forces with them to achieve mutual solubility. This solubility is used in organic synthesis to dissolve reactants, promote reactions, and separate products.
1- (2-cyanopyridine) -1H-pyrrole-2-ethyl acetate has a certain density, the relative density is about [X], which means that when it is mixed with liquids such as water, it will appear stratified according to the density difference. In chemical production and laboratory operations, preliminary separation operations can be carried out accordingly. At the same time, it also has a certain degree of volatility, which will evaporate slowly at room temperature. When storing and using, it should be sealed to prevent loss and impact on the environment. In addition, the compound may have a weak special odor. Although the odor has no substantial effect on its chemical properties, it can be used as a physical identification feature.

To prepare 1- (2-cyanobenzyl) -1H-indole-2-acetic acid, there are various methods.
First, indole is used as the starting point, and then formylated to obtain 2-formyl indole. Then, the condensation reaction with cyanobenzyl reagent is carried out, in which a base may be required as the catalyst to merge the two phases to form 1- (2-cyanobenzyl) -1H-indole-2-formaldehyde. After the oxidation step, the aldehyde group is converted into a carboxyl group, and the final target is 1- (2-cyanobenzyl) -1H-indole-2-acetic acid. In this way, attention should be paid to the reaction conditions of each step, the temperature of formylation, the amount of catalyst; the strength of the base during condensation, the reaction time; the choice and ratio of the oxidizing agent during oxidation, all of which are related to the yield and purity of the product.
Second, using 2-methylindole as the raw material, the methyl group is pre-cyanobenzylated, and then the other end is converted into a carboxyl group under suitable conditions. When cyanobenzylating, choose the appropriate solvent and catalyst to ensure the smooth reaction. Subsequent carboxylation steps, or require specific reagents and the environment, or oxidation, or by other chemical reactions, the methyl group is gradually changed carboxyl group, but also need to carefully observe the reaction process, due to changes in conditions, or side reactions, affecting the quality of the product.
Third, it can still be spliced and modified from compounds containing indole and acetic acid structural fragments. First find a suitable indole-containing fragment, which has an activity check point that can react with cyanobenzyl, and then insert the acetic acid-containing fragment in an ingenious way, or through esterification, amidation and other reactions, and then modify the overall structure. Introduce cyanobenzyl, and through multiple steps of delicate operation, obtain 1- (2-methylbenzyl) -1H-indole-2-acetic acid. There are many steps in this way, and it is necessary to precisely control each step of the reaction, so that the intermediates in each step can be obtained stably, so as to achieve the purpose of final synthesis.
All kinds of synthesis methods have their own advantages and disadvantages. When implementing, according to the availability of raw materials, cost considerations, and difficulty of reaction, choose carefully to make the synthesis efficient and economical, and obtain a pure product.

I don't know what you said about the market price of "1- (2-pyrimidinyl) -1H-imidazole-2-acetonitrile". This is a fine chemical substance, and its price is determined for many reasons.
First, the price of raw materials. The preparation of this compound requires specific raw materials. If the raw materials are produced less, difficult or difficult, the price must be high. This is the foundation for this substance, and the price will be high.
Second, the simplicity of the process. If the synthesis method requires multi-step reaction, and the conditions are harsh, such as temperature control, pressure control, special catalysts, etc., more manpower, material resources and time are required, and the cost will rise due to the complexity of the process, and the market price will also rise.
Third, the supply and demand of the market. If there are many people who want this compound, but the production is limited, the so-called "rare is expensive", its price will rise; on the contrary, if the supply exceeds the demand, the business will sell it, or the price will be reduced to promote it.
Fourth, the quality is divided. High purity, because it is more difficult to produce, is suitable for high standards, and the price is often higher than that of ordinary people.
However, I have not been involved in chemical trade, and I do not know the current market situation, so it is difficult to determine the exact price. If you want to know the details, you can consult the supplier of chemical raw materials, or check the professional chemical price information platform to get the actual price.

1 - (2-pyridyl) -1H-imidazole-2-ethanol, there are many things to pay attention to during storage and transportation.
First, the properties of this substance may vary from environment to environment. It should be placed in a cool, dry and well-ventilated place. If it is in a humid place, it may be damp and deteriorated, causing its chemical structure to change and affecting its function. And the temperature must also be carefully checked. Excessive temperature may cause it to decompose, volatilize, or even cause safety concerns; too low temperature or cause it to freeze, change its physical form, and is not conducive to subsequent use.
Second, when storing, it must be isolated from oxidants, acids, bases, etc. Due to their chemical activity, contact with their substances is prone to violent chemical reactions, or serious consequences such as fire and explosion. If it encounters a strong oxidizing agent, or triggers an oxidation reaction, a large amount of heat is released, which in turn causes danger.
Third, when transporting, the packaging must be solid and sealed. Choose suitable packaging materials to prevent leakage. If there is a leak during transportation, it will not only damage the material, but also pollute the environment and endanger the surrounding organisms. The means of transportation must also be clean and dry, and there should be no residual substances that can react with it. And the transportation personnel should be familiar with its characteristics and emergency treatment methods. They should inspect regularly on the way. If there is any abnormality, they should be disposed of immediately.
Fourth, the label logo is indispensable. On the packaging, the name, nature, danger warning and other information should be clearly marked. This is convenient for storage and transportation personnel to quickly identify, properly handle according to their characteristics, and also provide key information for emergency rescue. In short, the storage and transportation of this object must be carefully considered and strictly followed to ensure safety.
