4-Methylthiazole-5-formaldehyde is an organic compound with the following physical properties:
Appearance properties: At room temperature and pressure, it is mostly colorless to light yellow liquid or solid, depending on the purity and crystallization conditions. When pure, it may be transparent to yellowish clear liquid, and when low temperature, it may crystallize into a solid with a certain luster.
Melting point: Melting point is about 48-52 ° C. At this temperature, the substance changes from solid to liquid. The boiling point is about 243-245 ° C. At this temperature, the liquid quickly turns into a gaseous state.
Density: The relative density is about 1.24 (water = 1), which means that under the same volume, the mass of 4-methylthiazole-5-formaldehyde is heavier than that of water.
Solubility: Slightly soluble in water, because water is a polar molecule, the compound contains hydrophobic thiazole rings and methyl groups, which cause it to interact weakly with water. However, it is soluble in common organic solvents, such as ethanol, ether, acetone, etc., because these organic solvents and the compound can form intermolecular forces, such as van der Waals force, to help it dissolve.
Odor: It has a special pungent odor. This odor is derived from its sulfur heterocycle and aldehyde group structure. This odor or is pungent and has a certain stimulation to the sense of smell. < Br > Stability: relatively stable in normal environment, flammable in case of open flame and hot topic, because it contains flammable elements such as hydrocarbons. Contact with strong oxidants or react violently, because the aldehyde group is reductive and easily oxidized.

The chemical synthesis method of 4-methylthiazole-5-formaldehyde has not been described in detail in ancient books, but according to today's chemical classics and previous experience, it can also be numerically obtained.
First, the heterocyclic compound containing sulfur and nitrogen can be used as the starting material, and the nucleophilic substitution reaction can be started. For example, select a suitable halogenated alkane and a heterocyclic precursor containing sulfur and nitrogen. Under the catalysis of a base, the halogenated alkane atom and the activity of the heterocyclic precursor undergo nucleophilic substitution at the check point, and a methyl group is introduced. Subsequently, the appropriate functional group is converted into an aldehyde group through a specific oxidation step. In this process, the reaction conditions such as temperature, solvent and reactant ratio need to be carefully adjusted. If the temperature is too high or too low, the reaction rate can be abnormal and the yield is poor; the polarity and solubility of the solvent also have a significant impact on the reaction process.
Second, the cyclization reaction strategy can be used. Using the chain precursor containing carbon, sulfur and nitrogen as raw materials, under suitable catalyst and reaction conditions, intramolecular cyclization occurs to construct a thiazole ring structure. When constructing the ring structure, the substituent of the precursor is cleverly designed to make the methyl group in a suitable position in advance. After the cyclization is completed, the specific group is modified into an aldehyde group through a selective functional group conversion reaction. The key to this method lies in the selectivity and yield of the cyclization reaction, the selection and dosage of the catalyst, and the precise control of the reaction environment.
Third, it can be improved by referring to the synthesis paths of related similar compounds reported in the literature. Refer to the synthesis of similar structural compounds, and make appropriate adjustments to the reaction steps and reagents according to the structural characteristics of 4-methylthiazole-5-formaldehyde. Such as changing the activity of the substitution reagents and optimizing the reaction sequence to meet the synthesis requirements of the target product. This process requires in-depth study of many literatures, extraction of essence, and flexibility to find an efficient synthesis method.

4-Methylthiazole-5-formaldehyde is a very important organic compound, and there are many points to be paid attention to during storage and transportation.
First of all, storage, this compound should be stored in a cool, dry and well-ventilated place. Because it may be more sensitive to heat, high temperature is easy to cause chemical reactions, resulting in quality damage. And be sure to keep away from fires and heat sources, because flammable substances are exposed to open flames, hot topics, or the danger of fire or even explosion.
Furthermore, the humidity of the storage environment needs to be strictly controlled. Humid environment or make 4-methylthiazole-5-formaldehyde hygroscopic, which will affect its stability or cause it to deteriorate. It should be placed in a sealed container to prevent excessive contact with air and avoid oxidation and other reactions.
As for transportation, it is necessary to strictly follow the relevant regulations on the transportation of dangerous chemicals. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment to prevent accidents. When handling, it should be handled lightly and unloaded. It must not be operated brutally to avoid damage to the packaging container and leakage of 4-methylthiazole-5-formaldehyde.
If a leak occurs during transportation, personnel in the leakage contaminated area should be quickly evacuated to a safe area, quarantined, and strictly restricted access. Emergency responders are required to wear self-priming filter gas masks (full masks) and gas suits to cut off the source of leaks as much as possible. Small leaks can be mixed with sand, dry lime or soda ash and collected in a dry, clean, covered container. Large leaks need to be embanketed or dug for containment, covered with foam to reduce vapor hazards, and then pumped to a tanker or special collector for recycling or transportation to a waste disposal site for disposal.

The market price of 4-methylthiazole-5-formaldehyde is difficult to determine. Market prices often change due to various reasons, such as origin, quality, supply and demand conditions, which can make them different.
Looking at the market of chemical materials in the past, if it is an ordinary product, in general transactions, its price may vary according to quantity. When the quantity is small, or because it needs special storage and transportation methods, the cost is slightly higher, and the price per gram may reach tens of gold.
If the purchase quantity is slightly larger, the price per gram may be reduced to a few gold to more than ten gold due to the benefit of scale and cost reduction. However, this is only speculation. Due to the fickle chemical market, new processes, policies or emergencies can make prices fluctuate.
And different suppliers have different prices due to their different channels, costs and operations. Therefore, if you want to know the exact price, you need to consult the chemical raw material supplier in person, or check the latest price of the chemical trading platform.
