When preparing some functional materials, its participation in reactions can improve the properties of materials, such as enhancing material stability, adjusting material optical properties, etc., and then promote the development and application of new materials, which contributes to the development of materials science. In short, 4-methyl-1,3-thiazole-2-carboxylic acid has key uses in many important fields and is of great significance to promote the development of related industries.

4-Methyl-1,3-thiazole-2-carboxylic acid, which is an organic compound. Its physical properties are as follows:
Viewed at room temperature, it is mostly white to quasi-white crystalline powder, and its powder is delicate and slightly shiny under light or visible. This is because the molecular arrangement and crystal structure make its surface reflect and refract light, so it is like this.
Smell, there is little obvious smell, or only a very weak and imperceptible smell. The cover is not easy to emit a significant smell because of its stable molecular structure and few volatile components.
As for solubility, it is slightly soluble in organic solvents, such as ethanol and dichloromethane. Ethanol is a common organic solvent, and it can be partially dissolved by weak interactions such as hydrogen bonds with 4-methyl-1,3-thiazole-2-carboxylic acid molecules. In water, its solubility is poor. Water is a solvent with strong polarity, and it is difficult to dissolve effectively with the intermolecular force of the compound.
When it comes to the melting point, it is about a specific temperature range, which is determined by the intermolecular force. When the temperature rises, the thermal motion of the molecule intensifies. When the melting point is reached, the intermolecular force is overcome, the lattice structure disintegrates, and the substance changes from solid to liquid. Its melting point characteristics are of great significance in the purification and identification of compounds.
In addition, its stability is quite high, and it is not easy to react with common components in the air, such as oxygen and carbon dioxide, under general environmental conditions. This is due to the strength and structural stability of the chemical bonds in the molecule, which allows the compound to maintain its own structure and properties under normal conditions.

The synthesis method of 4-methyl-1,3-thiazole-2-carboxylic acid has been around for a long time, and it has also evolved over time. In the past, thioacetamide and α-halogenated ketones were often used as starting materials.
First, thioacetamide is blended with an appropriate amount of alkali. The alkali solution, such as sodium hydroxide, is slowly reacted at a moderate temperature, such as 40-60 degrees Celsius. Wait for the thioacetamide to fully react with the base to form the corresponding sulfur negative ion intermediate. At the same time, α-halogenated ketones, such as α-chloroacetone, are slowly added dropwise to the above reaction system. This process requires careful control of the dripping speed to prevent the reaction from being too violent. The nucleophilic substitution reaction between α-halogenated ketones and sulfur anion intermediates occurs rapidly, and the 4-methyl-1,3-thiazole-2-carboxylic acid precursor is preliminarily formed through cyclization.
However, this product contains many impurities and needs to be further purified. In traditional methods, a suitable solvent is often selected by recrystallization, such as ethanol-water mixed solvents, and recrystallization is repeated according to the difference in solubility to obtain a purer product.
Today, technology is changing with each passing day, and there are also emerging synthetic pathways. For example, the transition metal catalysis method uses complexes of metals such as palladium and copper as catalysts, halogenated thiazole derivatives and methylation reagents, with the assistance of ligands, under mild conditions, such as room temperature to 80 degrees Celsius, to achieve the construction of 4-methyl-1,3-thiazole-2-carboxylic acid. This method has good selectivity, high yield, and mild reaction conditions without high temperature and pressure, and is gradually favored by many synthesizers.
Another exploration of biosynthesis. With the catalytic properties of microorganisms or enzymes, biological metabolic pathways can be simulated in vivo or in vitro to achieve the synthesis of target products. This path is green and environmentally friendly, but the technology is still in the development stage. To achieve maturity, many scientific researchers still need to study it relentlessly.

I look at your question, but I am inquiring about the price range of 4 - Methyl - 1,3 - thiazole - 2 - carboxylic acid in the market. However, the price of this product is difficult to determine. Due to the ever-changing market conditions, many factors can cause its price to fluctuate.
First, the situation of supply and demand is the main reason. If there are many people who want it, and the supply is small, the price will rise; on the contrary, if the supply exceeds the demand, the price may drop. Second, the place of origin also matters. Different origins, due to the different costs of raw materials, production processes, and transportation, have different entry prices. Third, the difference in quality grades also makes the price different. High quality, the price is often higher than ordinary.
According to past examples and market speculation, this product is in the market. If it is an ordinary commercial grade and purchased in bulk, the price per kilogram may be between hundreds and thousands of yuan. However, this is only a rough estimate. The actual price must be checked in detail in the current chemical raw material market and consulted with suppliers to obtain the exact number.
