4-Methylthiothiazole is also an organic compound. It has unique physical properties. Looking at its shape, at room temperature, it is usually a colorless to light yellow liquid. Its shape is clear and transparent, like jade dew, without suspended impurities, pure and good quality.
In terms of its smell, it has a strong and special smell, its pungent and penetrating smell, and it is unforgettable. Although it has a pungent feeling, it is also one of its signs.
As for the boiling point, it is about a specific temperature range. This temperature can make it change from liquid to gas. The boiling point value may vary slightly due to environmental factors, but the approximate range can be found. This boiling point characteristic is very important in its separation, purification and related chemical operations. According to this, distillation and other means can be used to obtain pure substances.
Its density is also a certain value. Compared with water, it is either light or heavy. This density characteristic can be identified and analyzed in the process of mixing and delamination of substances. And its solubility shows good affinity in organic solvents, and there are many soluble ones. For example, common organic solvents such as ethanol and ether can dissolve with it to form a uniform solution. In water, the solubility is poor, and the two meet, often stratified, with the upper layer being water and the lower layer being 4-methylthiothiazole. This difference in solubility is commonly used in chemical separation and reaction system construction.

4-Methylthiothiazole, which has unique physical properties. It is an organic compound with a unique structure. The molecule contains a thiazole ring and a methylthio group, which is important in the field of chemistry.
Looking at its physical properties, at room temperature, 4-methylthiothiazole is mostly liquid or solid, but it also changes depending on specific conditions. Its color is often nearly colorless to light yellow, slightly transparent in appearance, or slightly cloudy, and has a special smell, which is pungent and recognizable. Its boiling point and melting point are specific values due to intermolecular forces and structures. The boiling point is about a certain temperature range. At this temperature, the substance changes from liquid to gaseous state, and the melting point defines the transition between solid and liquid states.
As for chemical properties, 4-methylthiothiazole is reactive. The presence of thiazole rings allows it to participate in a variety of chemical reactions. Methylthio groups also play a role, which can contribute electrons and affect the electron cloud distribution of molecules, which in turn affects reactivity. It can react with electrophilic reagents, which tend to have high electron densities. The electron cloud density near methylthio can attract electrophilic reagents and cause reactions to occur. It can also interact with nucleophiles, which are rich in electrons and can attack the positive check point on the thiazole ring, thereby initiating chemical reactions. In addition, under appropriate conditions, 4-methylthiothiazole can participate in the substitution reaction, and the atoms or groups on the methylthio or thiazole ring can be replaced by other atoms or groups to generate new compounds. And in the redox reaction, 4-methylthiothiazole can also exhibit characteristics, or act as a reducing agent, giving electrons, or under the action of an oxidant, undergo structural changes and participate in the oxidation process.

The preparation method of 4-methylthiothiazole, although it is not contained in the ancient book "Tiangong Kaiwu", can be found by today's chemical preparation method.
One method is obtained by condensation reaction of sulfur-containing compounds and nitrogen-containing and carbon-containing raw materials. If appropriate thiols and halogenated acetonitrile or similar cyanohalides are used in suitable solvents and catalyzed by bases, condensation cyclization can occur. First, the thiol is mixed with a base to form a thiol salt. This thiol salt is nucleophilic and can attack the carbon attached to the halogen atom of halogenated acetonitrile. The halogen atom leaves to form a carbon-sulfur bond, and then the cyanyl group in the molecule is cyclized with another active check point. After a series of electron rearrangements and reactions, 4-methylthiothiazole is formed.
The second method uses thiazole derivatives as starting materials to carry out thiomethylation reactions. Select a suitable thiazole compound and react with methylation reagents and vulcanization reagents under specific reaction conditions. Commonly used methylation reagents such as iodomethane, vulcanization reagents such as sodium hydrosulfide or thiourea, etc. The hydrogen atom at a specific position on the thiazole ring is removed in a basic environment or in the presence of a catalyst to form a carbon negative ion. This carbon negative ion interacts with a vulcanizing agent to form a sulfur-containing intermediate first, and then reacts with a methylating agent to introduce methylthio, resulting in 4-methylthiothiazole.
In addition, a heterocyclic synthesis method is used to construct a thiazole ring from more basic raw materials and introduce methylthio at the same time. For example, alpha-halogenated ketones are reacted with thiourea and methyl-containing sulfur sources in multiple steps to form thioamide intermediates first, and then cyclized within the molecule to construct thiazole rings. During the cyclization process or subsequent steps, methylthio groups are ingeniously introduced to achieve the preparation of 4-methylthiothiazole.
During the preparation process, attention should be paid to the precise control of reaction conditions, such as temperature, pH, reaction time, etc., which are all related to the purity and yield of the product. Different raw materials and methods have their own advantages and disadvantages. The preparation method must be carefully selected according to actual needs and available raw materials, equipment and other factors.

It is difficult to determine the price range of 4-methylthiothiazole in the market. Looking at "Tiangong Kaiwu", although it describes many products and processes in detail, it is not as good as 4-methylthiothiazole, so its price cannot be found from the book.
The price of 4-methylthiothiazole is affected by many factors. The first one to bear the brunt is the cost of production. The price of raw materials and the simplicity of the preparation method are all related to it. If the raw materials are rare, the preparation requires exquisite and complicated processes, and consumes a lot of manpower and material resources, the price will be high.
Furthermore, the state of market supply and demand is also the key. If there are many people who want it, but there are few products, the supply is in short supply, and the price will rise; on the contrary, if the market is saturated and the supply exceeds the demand, the price will decline.
In addition, the quality also affects the price. High-quality 4-methylthiothiazole, with few impurities, high purity, or suitable for high-end fields, its price should be higher than ordinary ones.
And the price varies from region to region. Traffic congestion and poor market conditions in various places all cause price fluctuations. Generally speaking, the price may range from tens of yuan per kilogram to hundreds of yuan per kilogram, but this is only a rough estimate. The actual price depends on the specific time, quality and market conditions.
