Methylthiopheno [2,3-b] pyridine-2-carboxylic acid ester, this is an organic compound. Looking at its physical properties, under normal conditions, or as a solid state, its melting point, boiling point and other data depend on the intermolecular forces and the degree of structural compactness. Because the molecule contains aromatic rings and polar functional groups, the intermolecular forces are complex, and the melting point may be higher, requiring more external energy to destroy the lattice structure and make it melt.
In terms of solubility, the polar carboxylic acid ester group and the non-polar aromatic ring may exhibit unique performance in organic solvents. Polar organic solvents, such as methanol, ethanol, etc., can form hydrogen bonds or have similar polarity to carboxylic acid ester groups, or have certain solubility to them; non-polar organic solvents, such as n-hexane, etc., have certain similarity to the aromatic ring structure, or have partial solubility to it. However, in water, its overall hydrophobicity is strong, and its solubility is not good.
Furthermore, its appearance may be white to light yellow powder or crystalline, which is related to the molecular arrangement and light reflection and absorption characteristics. Pure ones have uniform appearance and single color. If they contain impurities, they may cause changes in appearance, color and morphology. Its density is also related to the molecular weight and the degree of molecular accumulation, and the relative density may vary depending on the specific structure and crystal form.

There are various ways for the synthesis of thiopheno [2,3-b] pyridine-2-carboxylic acid esters. One is through the condensation reaction of thiophene and pyridine derivatives. Take the appropriate thiophene derivative first, so that it meets the pyridine derivative under specific reaction conditions. Among them, the choice of reaction solvent is quite important, and organic solvents such as toluene and dichloromethane are often preferred, because they can make the reactants well dissolved and facilitate the reaction. At the same time, suitable catalysts, such as metal catalysts, need to be introduced to promote the reaction rate and make it easier to reach the desired product.
Furthermore, it can be obtained by esterification of thiophenopyridine compounds containing carboxyl groups with methanol. In this process, acid catalysts are indispensable, and common sulfuric acid and p-toluenesulfonic acid can play this role. During the reaction, temperature control is also crucial, and it is usually maintained in a moderate warm state, so that the reaction can occur smoothly without overheating and side reactions.
Another method is to gradually build a molecular structure from basic organic raw materials. First, the basic fragments of thiophene ring and pyridine ring are prepared, and then they are connected by chemical bonds in sequence to form methylthiopheno [2,3-b] pyridine-2-carboxylic acid ester. Although this path is a bit complicated, it may have unique advantages in the selectivity of raw materials and the control of the purity of the product. During the reaction process, the reaction conditions of each step, such as the proportion of reactants, reaction time, temperature, pH, etc., need to be carefully controlled to obtain satisfactory results. In short, there are various methods for synthesizing this compound, each with its own advantages and disadvantages, and it is necessary to weigh and choose according to actual needs.

I think what you are asking is about Methyl thieno [2,3 - b] pyridine - 2 - carboxylate in the market price range. However, the price of this unusual thing is easily influenced by many factors, and it is difficult to determine its price.
If this compound is used for scientific research, the purity requirements are very high, and the preparation process is complicated, so its price is not cheap. If its preparation requires special raw materials, or the process is cumbersome, the cost will increase, and the price will also rise. And the market supply and demand relationship is also the key. If there are many people who want it, and the supply is scarce, the price will rise; on the contrary, if the supply is sufficient and the demand is small, the price may fall.
In addition, different suppliers have different pricing due to their cost considerations and market strategies. At professional chemical reagent suppliers, prices may be high due to brand reputation and product quality assurance; while some emerging or small suppliers may have low prices in order to compete for the market.
As far as I know, there is no exact information on its price range. For details, you can go to the professional chemical reagent trading platform to see the quotations of different merchants; or consult the chemical reagent supplier and ask their price in detail to get a more accurate price range.
