2-Acetamido-5-fluoropyridine ,97%

I look at your question, and I am inquiring about the ignition point of 2-Acetamido-5-fluoropyridine (2-Acetamido-5-fluoropyridine, 97%). However, this chemical ignition point information is not recorded in "Tiangong Kaiwu". The author of "Tiangong Kaiwu", written by Yingxing Song in the Ming Dynasty, describes the skills of hundreds of workers, which are related to agriculture, mulberry, hardware, pottery and other industries. However, most of them involve traditional crafts, and the ignition point of these fine chemicals is rarely mentioned.
If you want to know the ignition point of 2-Acetamido-5-fluoropyridine today, you should seek modern chemical classics, professional databases or experimental reports. Since the development of chemistry, there are many categories and new things are increasing day by day, which cannot be included in ancient books. Although "Tiangong Kaiwu" has made great contributions to the craftsmanship of the past, it is difficult to answer this question. It is advisable to follow today's scientific methods, or check professional chemical manuals, or interview chemical experts, or observe experimental records, in order to obtain the exact number of ignition points.

I think what you are asking is about "2-Acetamido-5-fluoropyridine, 97% melting point geometry". However, in Tiangong Kaiwu, there is no description of the melting point of such chemicals. Gai "Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty. It is detailed in ancient agricultural and handicraft production technologies. At that time, chemistry was not as prosperous as it is today, and there is no record of the melting point of such fine chemicals.
If you want to know the melting point of "2-acetamido-5-fluoropyridine, 97%" today, you should consult modern chemical classics, professional databases, or experts and scholars in the field of chemistry. It must be able to tell you the exact value of the melting point of this thing with precise experimental data and scientific knowledge. Although "Tiangong Kaiwu" is a masterpiece of ancient Chinese science and technology, it is limited by the times, and it is difficult to answer this modern chemical question.

2-Acetamido-5-fluoropyridine, with a purity of 97%, is used in many fields such as medicine and chemical industry.
In the field of medicine, it can be used as a key intermediate for the creation of new drugs. Drug developers modify and modify its structure to develop innovative drugs with high efficiency and low toxicity. For example, in the process of anti-tumor drug development, this compound may be able to splice with other active groups through specific chemical reactions to construct drug molecules that target tumor cells. By interfering with specific physiological processes of tumor cells, it can inhibit tumor growth and spread.
In the chemical industry, it plays an important role in organic synthesis. As a starting material or intermediate, it participates in the synthesis of many complex organic compounds. For example, in the manufacture of fine chemicals, it can be converted into compounds with special functions through a series of organic reactions, such as new dyes, high-performance material additives, etc. With its unique chemical structure, it endows the final product with excellent optical, electrical or chemical stability and other properties. At the same time, in material science research, it can be used to prepare polymer materials with special properties. By introducing them into the main chain or side chain of the polymer, the physical and chemical properties of the polymer can be changed and the application range of the material can be expanded.

2-Acetamido-5-fluoropyridine (2-Acetamido-5-fluoropyridine), with a content of 97%, is synthesized as follows:
5-fluoropyridine is often used as the starting material. First, 5-fluoropyridine reacts with acetic anhydride in the presence of a suitable catalyst. This catalyst can be selected from Lewis acids with mild catalytic activity, such as anhydrous zinc chloride. The reaction is carried out at a suitable temperature, usually under the condition of heating and refluxing, to induce the nucleophilic substitution reaction of the nitrogen atom of 5-fluoropyridine with acetic anhydride to generate 2-acetamido-5-fluoropyridine. < Br >
During the reaction process, it is necessary to pay close attention to the temperature and reaction time of the reaction system. If the temperature is too low, the reaction rate will be slow and it will be difficult to obtain the ideal yield; if the temperature is too high, it may cause side reactions and affect the purity of the product. The reaction time also needs to be precisely controlled. According to the monitoring of the reaction process, the consumption of raw materials and the formation of products are generally observed by thin layer chromatography (TLC) technology. The reaction can only be stopped when the reaction of raw materials is basically complete.
After the reaction is completed, the reaction mixture is post-treated. The mixture is first extracted with an appropriate organic solvent, such as dichloromethane, to separate the organic phase. Subsequently, the organic phase is dried with anhydrous sodium sulfate to remove the moisture contained therein. Then, by means of reduced pressure distillation, the organic solvent is removed, and the crude product is preliminarily obtained.
Finally, the crude product is purified. The purification method can be used column chromatography, using silica gel as the stationary phase, selecting a suitable eluent, such as the mixed solvent of petroleum ether and ethyl acetate. After this step, high purity 2-acetamido-5-fluoropyridine can be obtained, and its content can reach 97%. In this way, the synthesis of 2-acetamido-5-fluoropyridine is completed.

The market price of 2-acetamido-5-fluoropyridine, with a content of 97%, often fluctuates due to a variety of factors. One of these factors is related to the difficulty of its preparation. If the preparation process is cumbersome and requires exquisite skills and rare raw materials, the cost will be high, and the price will also rise. Second, the price of raw materials has a great impact on it. If raw materials are scarce and difficult to find, or the price changes due to the current situation, origin, etc., the price of the product will also be implicated. Furthermore, the supply and demand situation of the market has a huge influence on the price. If there are many people who want them, and there are few people who supply them, the price will rise; conversely, if the supply exceeds the demand, the price will fall.
Today, in all kinds of transactions in the market, the price is roughly around tens to hundreds of yuan per gram. However, this is only an approximate number, not a definite one. In professional chemical raw material trading platforms, or due to bulk purchase, you can get preferential prices; in niche channels, or due to the complexity of the circulation link, the price may be higher. In order to know its accurate market price, you need to carefully observe the real-time market conditions and compare the quotations of different suppliers many times to get a more accurate number.
