Its particle size is evenly distributed, and the particles are small. Viewed under light, it shimmers shimmeringly, like stars. < Br >
Smell the smell, close to the light smell, you can smell a slight and specific smell, this smell is not pungent stench, nor is it fragrant, but a unique smell, with a little bit of chemical unique cold.
As for the melting point, after rigorous measurement, it is about [specific melting point value] ℃. When the temperature gradually rises, the substance slowly melts from a solid state to a liquid state, just like the initial melting of ice and snow, quietly changing its form.
In terms of solubility, this substance exhibits different dissolution properties in organic solvents. In halogenated hydrocarbon solvents such as dichloromethane and chloroform, the solubility is still good. When put into it, with a little stirring, it gradually dissipates into the solvent, forming a uniform solution, just like salt fused into the water, without a trace. In water, its solubility is quite limited, only slightly soluble, and most of them are still suspended in the water as solid particles, like gravel in a stream, which is difficult to blend. The measurement of the density of
also has its value, which is about [specific density value] g/³ cm. Compared with common lightweight substances, its density is slightly higher, and holding a container containing the substance can feel a little sinking.
These physical properties are of important reference value in applications in chemical, pharmaceutical, and other fields, and are related to the subsequent processing, reaction, and use of the substance.

2-Amino-3-cyano-4-chloro-5-formylthiophene (2-Amino-3-cyano-4-chloro-5-formylthiophene), the content is 98%, and the synthesis method is as follows:
The starting material is often selected from suitable sulfur-containing compounds and reagents containing corresponding groups such as nitrogen, cyano and chlorine atoms. The first step is to carefully design the reaction path so that the sulfur-containing compound and the specific halogen undergo nucleophilic substitution reaction under suitable conditions. The key to this reaction is to precisely control the reaction temperature, reaction time, and the type and amount of base used, so that the reaction can smoothly generate a preliminary sulfur-containing skeleton with intermediates that can be further modified.
Then, for this intermediate, a cyanation reagent is used to introduce a cyanide group in the presence of an appropriate catalyst. This process requires attention to the activity and selectivity of the catalyst to prevent side reactions from occurring and affecting the purity and yield of the product. After
, the intermediate is chlorinated, and a suitable chlorination reagent is used to control the reaction conditions, so that the chlorine atom precisely replaces the hydrogen atom at the target position. In this step, the choice of chlorination reagent, the pH of the reaction system, and the precise control of the reaction temperature are all crucial.
Finally, a formylation reaction is carried out to introduce formyl groups. Classical formylation reagents can be selected, such as reacting with intermediates under the catalysis of specific Lewis acids. In this step, attention should be paid to the reactivity of the formylation reagent, and the catalyst and solvent should be selected reasonably to promote the efficient reaction while avoiding overreaction or formation of other impurities.
After each step of the reaction, suitable separation and purification methods such as column chromatography and recrystallization are required to ensure the purity of the intermediate, and then to ensure the high purity (98%) of the final product 2-amino-3-cyano-4-chloro-5-formylthiophene.

2-Amino-3-cyano-4-chloro-5-formylthiophene, with a content of 98%. This is a chemical substance. When storing, many matters need to be paid attention to.
Bear the brunt, temperature is crucial. This substance should be stored in a cool place, due to high temperature or changes in its properties. If the temperature is too high, it may cause a chemical reaction, causing its purity to be damaged or even forming other impurities. Therefore, it is crucial to choose a storage environment with stable temperature and low temperature.
Humidity should not be underestimated. Humid environment may make the substance damp, which in turn affects its quality. Water vapor may react with substances to change their chemical structure. Therefore, the storage place must be kept dry, and the ambient humidity can be reduced with the help of desiccants and other items.
Furthermore, light also affects it. Light may cause photochemical reactions to occur, resulting in changes in components. Therefore, it should be stored in a dark place, such as in a dark container or in a corner of a warehouse without light exposure.
In addition, this chemical has certain chemical activity and needs to be properly isolated from other substances. Do not store with strong oxidants, strong acids, strong bases, etc., to prevent violent reactions, endangering safety and damaging their quality.
At the same time, the choice of storage container is also very important. Containers of suitable materials must be selected to ensure that they do not corrode the substance and have good sealing properties to prevent the substance from evaporating or reacting with outside air components.
During storage, it should also be checked regularly. Check the container for damage and signs of deterioration of the substance, so that problems can be detected and properly disposed of in time. In this way, 2-amino-3-cyano-4-chloro-5-formylthiophene can maintain good quality and stability during storage.

I look at your question, but I am inquiring about the market price of 2-amino-3-cyano-4-chloro-5-formylthiophene (98% purity). However, the market price of this compound often varies due to various factors, which is difficult to determine.
In the past, the price of the contents of "Tiangong Kaiwu" varied according to the place of origin, season, supply and demand. The same is true today. The difficulty of its preparation, the price of the required raw materials, and the amount of market demand are all important factors affecting its price.
If it is difficult to prepare, rare raw materials are required, and purification to 98% purity is not easy, its price must be high. And if the market demand for this product is strong, the supply is in short supply, and the price should also rise. On the contrary, if the preparation is simple, the raw materials are common, and the market demand is low, the price may be lower.
Furthermore, the pricing of different suppliers is also different. Large merchants or because of the scale effect, the cost is controllable, and the pricing is relatively close to the people; small merchants or because of the high cost, the pricing is slightly higher. However, if you want to know the exact market price, you can get a near real-time price by consulting chemical raw material suppliers and chemical trading platforms.
