4-Amino-2-fluoropyridine, with a content of 97%, has many physical properties. Its color is white to light yellow powder or crystal, and it exists stably at room temperature. Looking at its shape, it is often in the shape of fine powder or tiny crystals, with uniform and fine texture.
When talking about the melting point, it is between 155-159 ° C. The characteristics of the melting point are the key indicators for identifying this substance and judging the purity. When heated to this temperature range, the substance gradually melts from solid to liquid, and this process is quite clear.
Its solubility is also characteristic, slightly soluble in water, but better soluble in organic solvents such as methanol, ethanol, dichloromethane, etc. In organic solvents, it can form a uniform solution, which is widely used in organic synthesis and other fields.
Furthermore, this material has a certain smell, but it is not pungent and intolerable, and belongs to the category of mild odor. The characteristics of its odor are also one of the aids in distinguishing substances. In terms of density, although there is no precise constant widely circulated, its density is similar to that of common organic compounds. In actual operation and storage, this characteristic is related to the quantity of the substance and the space it occupies.
Its vapor pressure is low at room temperature, and it is not easy to evaporate, making it relatively convenient to store. This physical property allows it to be stored for a long time in conventional environments without excessive loss due to volatilization. In summary, many physical properties of 4-amino-2-fluoropyridine are of great significance for applications in chemical, pharmaceutical and other fields.

4-Amino-2-fluoropyridine, with a content of 97%, has relatively stable chemical properties. Among this compound, amino and fluorine atoms endow it with unique chemical activities. Amino groups can participate in a variety of nucleophilic reactions, while fluorine atoms have strong electronegativity, which affects the electron cloud distribution of molecules, thereby affecting the reactivity and selectivity.
Under normal conditions, the substance can maintain stability in a dry environment without the interference of active reagents. However, in case of strong oxidants, the amino group may be oxidized, resulting in changes in its structure and properties. If it is placed in a strongly acidic or alkaline environment, its original structure will be destroyed due to the alkalinity of amino groups, the weak alkalinity of pyridine rings, the replaceability of fluorine atoms, or the initiation of acid-base reactions, substitution reactions, etc.
However, with a purity of 97%, the impurity content is relatively low, which has a limited impact on its stability. As long as the storage conditions are suitable, such as sealed and stored in a cool, dry place, protected from strong light and hot topics, its chemical properties can remain relatively stable for a certain period of time, which can meet the needs of experiments and production in many fields such as chemical synthesis.

I look at your question, and I am inquiring about the market price of 4-amino-2-fluoropyridine (97% content). However, this price cannot be generalized, and it varies due to many reasons.
In the past, the price of chemical raw materials was often tied to the trend of supply and demand. If the demand for this material is strong and the supply is limited, the price will tend to rise; on the contrary, if the supply exceeds the demand, the price may drop. And its preparation cost is also the key. The price of raw materials, the simplicity of the process, and the amount of energy consumption all affect its cost, which in turn affects the selling price.
In addition, the market conditions are changing rapidly, and there are differences in different seasons. In a good year, the price may be slightly lower due to the shortage of raw materials and the increase in production capacity; in an sorry year, the price may rise due to the shortage of raw materials and disasters. The differences in regions cannot be ignored. The convenience of transportation and storage costs vary from place to place, and the price varies.
As for the exact price, it is difficult to determine. You may need to ask the chemical market merchants, traders, or recent transaction records to obtain a relatively accurate figure. Probably due to the intertwining of the above factors, in order to know the market price of 4-amino-2-fluoropyridine (97%), it is still necessary to study the current market situation carefully and not jump to a conclusion.

4-Amino-2-fluoropyridine with a content of 97%. The preparation process is as follows:
2-fluoropyridine is used as the starting material. First, 2-fluoropyridine is nitrified. This step requires adding an appropriate amount of nitrifying reagent, such as mixed acid (mixed solution of nitric acid and sulfuric acid), in a suitable reaction vessel under specific reaction conditions. During the reaction, the temperature, reaction time and the ratio of reagents should be precisely controlled, so that 2-fluoropyridine can be introduced into nitro groups at specific positions on the pyridine ring to generate 2-fluoro-4-nitropyridine.
Subsequently, 2-fluoro-4-nitropyridine is reduced to convert nitro groups to amino groups. The commonly used reduction method is catalytic hydrogenation, and a suitable catalyst, such as palladium carbon (Pd/C), needs to be selected to react under hydrogen atmosphere and specific pressure and temperature conditions. In this process, hydrogen reacts with nitro groups under the action of catalysts, and gradually reduces them to amino groups, eventually generating 4-amino-2-fluoropyridine.
During the entire preparation process, each step of the reaction requires strict control of the reaction conditions. After the reaction is completed, separation and purification methods such as distillation, recrystallization, and column chromatography are required to obtain high-purity 4-amino-2-fluoropyridine products, ensuring that their content reaches 97%.
