Ethyl 2-bromo-1, what are the physical properties of 3-thiazole-5-carboxylate

Ethyl-2-bromo-1,3-thiazole-5-carboxylic acid ester, this is an organic compound. Its physical properties are quite important and are related to many chemical applications.

Looking at its morphology, it is often solid at room temperature and pressure, or a white to light yellow crystalline powder with a delicate appearance. This morphology is easy to store and transport, and it is easy to measure in many reaction systems.

When it comes to melting point, the compound has a specific melting point range, about [X] ° C to [X] ° C. Melting point is a key indicator to determine its purity. If the purity is high, the melting point range is narrow and close to the theoretical value; if it contains impurities, the melting point may be reduced, and the melting range is widened.

Solubility is also an important physical property. In organic solvents, such as common ethanol, acetone, dichloromethane, etc., it exhibits a certain solubility. In ethanol, moderate heating can better dissolve and form a uniform solution. This property is conducive to being used as a reactant or intermediate in organic synthesis reactions, enabling it to be fully dispersed in the reaction system and improving the reaction efficiency. However, the solubility in water is poor, because its molecular structure accounts for a large proportion of hydrophobic groups, resulting in weak interactions with water molecules.

In addition, the density of the compound is also an important parameter, about [X] g/cm ³. Density has reference value in material separation, purification and reaction system design. For example, in liquid-liquid extraction, effective separation from other substances can be achieved according to density differences.

In summary, the physical properties of ethyl-2-bromo-1,3-thiazole-5-carboxylic acid esters, such as morphology, melting point, solubility and density, are of great significance for their research, synthesis and application in the field of organic chemistry, and provide an important basis for chemists to carry out related work.

What is the market price of ethyl 2-bromo-1, 3-thiazole-5-carboxylate?

The market price of "ethyl 2 - bromo - 1,3 - thiazole - 5 - carboxylate" is an organic compound in the field of fine chemicals. However, the price of this product in the market often varies due to factors such as quality, supply and demand, and origin, and it is difficult to generalize.

Looking at the market of chemical products in the past, if the quality is high and the purity is very high, the price may be high; and if the purity is slightly lower or the impurities are slightly more, the price may be slightly lower. And if the market demand for this product is large at a certain time, and the supply is limited, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.

And the origin is different, the cost is also different. Where the production process is advanced and the raw materials are readily available, the cost of producing this product may be low, and the corresponding market price may be different. Therefore, to know the exact market price, it is necessary to carefully check the chemical product trading platform and consult relevant suppliers to obtain an accurate price. It must not be judged rashly based on past conditions alone, but based on real-time market dynamics.

Ethyl 2-bromo-1, 3-thiazole-5-carboxylate What are the precautions in storage and transportation?

When storing and transporting ethyl-2-bromo-1,3-thiazole-5-carboxylic acid ester, many matters need to be paid attention to. This substance has special properties and is quite sensitive to environmental conditions.

When storing, the first temperature should be controlled. It should be stored in a cool place. If the temperature is too high, it will easily cause decomposition or deterioration reactions, which will damage its own quality. The warehouse temperature should be maintained at 5 to 25 degrees Celsius, and the temperature fluctuation should not be too large.

Humidity is also the key. It should be avoided from humid environments, because it may cause adverse reactions such as hydrolysis after being damp. The relative humidity of the storage place should be kept between 40% and 60%. Dehumidification equipment can be used to maintain the appropriate humidity.

In addition, it is necessary to prevent it from coming into contact with oxidizing and reducing substances. Ethyl-2-bromo-1,3-thiazole-5-carboxylate is chemically active. In case of such substances, it may cause violent chemical reactions and cause danger. It should be stored separately and at a certain distance from other chemicals.

As for transportation, the packaging must be tight. Choose suitable packaging materials to ensure that there is no leakage during transportation bumps. The outer packaging should be clearly marked, indicating the characteristics of the item and precautions to facilitate the careful operation of the transporter.

The transportation process should also pay attention to the environment. Avoid direct sunlight, because light may accelerate its decomposition. At the same time, the driving should be smooth, reduce vibration and prevent package damage. If the transportation encounters hot weather, cooling measures should be taken, such as the use of refrigerated trucks, to ensure the safety of items.
