The physical properties of 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethylbenzofuran are related to many physical and chemical properties of this compound.
In this compound, methyl and pyridine-1-group are connected at a specific location, and trifluoromethyl is based on the benzofuran structure. In terms of physical properties, its appearance may be in a solid or liquid state, depending on its intermolecular forces and temperature conditions. Melting point and boiling point are also determined by factors such as intermolecular forces and molecular weight. Due to the interaction of different groups in the molecule, its melting and boiling point may be different from that of similar simple compounds.
Solubility is also an important physical property. Due to the presence of polar pyridyl groups and non-polar benzofurans and trifluoromethyl groups in the molecule, the solubility varies in different solvents. In polar solvents such as alcohols, or due to the formation of hydrogen bonds or dipole-dipole interactions between pyridyl groups and solvent molecules, there is a certain solubility; in non-polar solvents such as alkanes, due to the non-polar part of trifluoromethyl and benzofurans and the dispersion force between solvent molecules, there is also a corresponding dissolution performance.
In terms of its chemical properties, the nitrogen atom of the pyridyl group has a lone pair electron and is basic, which can react with acids to form corresponding salts. Methyl groups can participate in the substitution reaction, and under appropriate conditions, their hydrogen atoms can be replaced by other groups. The large electronegativity of the fluorine atom of the trifluoromethyl gene gives the compound a unique electronic effect, which affects the electron cloud density of the benzofuran ring, and then affects its electrophilic substitution or nucleophilic substitution activity. The structure of benzofuran also has its inherent reactivity, which can undergo cyclization, ring opening and other reactions, depending on the reaction conditions and the added reagents. Such various physical properties are of great significance in organic synthesis, drug development and other fields, and can be designed according to their characteristics.

I think your question is about "the chemical stability of 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethylpyridylamine". The stability of these chemical substances depends on many factors and is difficult to determine. The stability of
chemical substances often depends on their molecular structure, chemical bond energy and the environment in which they are located. In terms of its molecular structure, in 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethylpyridylamine, the atoms are connected in a specific way to form a unique spatial configuration. The interaction between methyl groups and pyridyl groups and trifluoromethyl groups may affect their overall stability. If all parts of the molecule are compatible with each other, the electron cloud is evenly distributed, and the chemical bond energy is high, the substance is relatively stable.
However, environmental factors are also crucial. Changes in temperature, humidity, light, pH and other conditions may affect its stability. Under high temperature, the thermal movement of molecules intensifies, or chemical bonds break; strong acid-base environment, or reacts with some of the groups, thereby changing its chemical structure and reducing stability.
Chemical reactivity is also related to stability. If the groups contained in this substance are prone to reactions such as addition, substitution, and oxidation with other substances, its stability is poor. For example, the nitrogen atom of the pyridine ring is alkaline to a certain extent, or can react with electrophilic reagents such as acids; methyl and trifluoromethyl also have their own reactivity.
In summary, in order to know the chemical stability of 3- (4 + methyl-pyridine-1-yl) -5 -trifluoromethylpyridylamine, it is necessary to conduct in-depth experimental investigations and consider the comprehensive effects of various factors. It cannot be assumed based on its chemical formula alone.

To prepare 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethylindole, the synthesis method is as follows:
First, nucleophilic substitution reactions in organic chemistry can be exploited through suitable starting materials. Compounds containing a pyridine structure with a departing group at a specific position are selected to react with a methyl-containing nucleophilic reagent to introduce methyl to construct a 4 + methyl-pyridine-1-yl structure. This process requires careful selection of reaction conditions, such as suitable bases, solvents and temperatures, to ensure selectivity and yield of the reaction.
Then proceed to the construction of the indole ring. Phenylhydrazine can be condensed with the corresponding β-dicarbonyl compound under acidic conditions to generate indole derivatives. In the reaction, the proportion of the reactants needs to be precisely controlled to make the reaction proceed in the direction of generating the target indole ring.
For the step of introducing trifluoromethyl, the common method is to use trifluoromethylation reagents. For example, using a nucleophilic trifluoromethylation reagent, under the action of a transition metal catalyst, reacts with an intermediate with a partially constructed structure to introduce trifluoromethyl into the 5-position of the indole ring. In this process, attention should be paid to the selection of catalysts and the anhydrous and oxygen-free operation of the reaction system to improve the reaction efficiency.
In the entire synthesis route, after each step of the reaction, the product needs to be purified by suitable separation and purification means, such as column chromatography, recrystallization, etc., to ensure the purity of the raw materials for the next reaction. At the same time, the reaction process should be closely monitored. The structure and purity of the intermediate product and the final product of the reaction should be confirmed by thin layer chromatography (TLC), nuclear magnetic resonance (NMR) and other analytical methods, so as to successfully synthesize 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethyl indole.

I look at your question, it is about "the price range of 3- (4 + methyl-pyridine-1-yl) -5-trifluoromethyl indole in the market". However, the price of the market often varies due to factors such as time and place, supply and demand, and quality, so it is difficult to determine the exact number.
Looking at the genus of "Tiangong Kaiwu", although all kinds of technical products are recorded, such fine chemical products may not have been involved at that time, and there is no old practice to follow their price. In today's world, this chemical substance may be used in pharmaceutical research and development, material science, etc., and its price varies depending on the use and purity.
If it is of high purity and suitable for high-end pharmaceutical developers, its price will be high, or it can reach hundreds or even thousands of yuan per gram. Due to the complicated process of R & D and purification, the cost is high. If it is for general industrial use, if the purity is slightly lower, the price may be slightly lower, ranging from tens to hundreds of yuan per gram.
And market supply and demand also affect its price. If there are many people in demand at a time, but there are few producers, the price will rise; on the contrary, if there is excess capacity and demand is low, the price may fall. In addition, the business environment and tax differences in various places also make prices different. Therefore, if you want to know the exact price range, you can obtain a more accurate figure by consulting chemical market merchants, chemical raw material suppliers, or referring to the quotations of professional chemical product trading platforms.
