2-Amino-4-trifluoromethylpyridine, the physical properties of this substance are quite impressive. In appearance, it is often in the state of white to light yellow crystalline powder. When viewed in sunlight, fine crystals can be seen flickering and shimmering, just like stars scattered. Its melting point is within a specific range. This characteristic makes it gradually transform from solid to liquid during heating at a certain precise temperature range, just like ice and snow melting in warm sunlight. This melting point characteristic provides a key reference for its various reactions and purification operations.
Furthermore, its solubility is also one of the important physical properties. In organic solvents, such as common ethanol, ether, etc., it shows a certain solubility. Ethanol is as clear as water. When it meets 2-amino-4-trifluoromethyl pyridine, the molecules interact, causing it to slowly integrate into it, just like salt dissolves in water, gradually forming a homogeneous liquid phase. In water, its solubility is relatively limited, like oil dripping into water, it is difficult to completely blend, and only a small amount of dispersion can occur.
In addition, the density of this substance also has its own unique value. Its density represents the mass of the substance in a unit volume, just like a scale for measuring the "compactness" of an object. This density characteristic is an indispensable consideration in many processes involving material mixing, separation, etc.
Furthermore, the vapor pressure of 2-amino-4-trifluoromethylpyridine also belongs to the category of its physical properties. At a specific temperature, it establishes a dynamic equilibrium between the gas phase and the condensed phase. The magnitude of the vapor pressure reflects the tendency of the substance to escape from the liquid or solid phase into the gas phase. Just like measuring the ability of a substance to "escape" from the gas phase, it is important for its storage, transportation and control of reaction conditions.

The synthesis method of 2-amino-4-trifluoromethyl pyridine has been around for a long time, and it has undergone evolution and is becoming more and more mature. The following are common synthesis paths:
First, pyridine derivatives are used as starting materials, and halogen atoms are introduced at specific positions in the pyridine ring by halogenation reaction. Subsequently, through nucleophilic substitution reaction, halogens are replaced by amino-containing reagents, and trifluoromethyl is introduced. In this process, the halogenation step needs to select suitable halogenating agents and reaction conditions to ensure that the halogen is accurately connected to the target check point. During nucleophilic substitution, the activity and selectivity of amino reagents are also crucial, and the reaction parameters, such as temperature and solvent, need to be carefully regulated to improve the reaction yield and purity.
Second, the coupling reaction strategy of metal catalysis is adopted. First, pyridine intermediates with specific functional groups are prepared, and then they are coupled with reagents containing trifluoromethyl and amino groups by means of metal catalysts, such as palladium and copper. The activity of metal catalysts, the selection of ligands, and the pH of the reaction system all have a profound impact on the reaction process. Precise control of these conditions can achieve efficient and highly selective synthesis.
Third, the target molecule is constructed by cyclization of compounds containing trifluoromethyl groups and raw materials containing amino and pyridine structures. This path requires clever design of the raw material structure and the use of suitable reaction conditions, such as high temperature and specific catalysts, to promote the cyclization process. In the meantime, the matching degree between the activity of the raw material and the check point of the reactivity is extremely critical, and the reaction route needs to be carefully planned to achieve the ideal synthesis effect.
Synthesis of 2-amino-4-trifluoromethylpyridine, each method has its advantages and disadvantages, and it is necessary to carefully select the appropriate synthesis method according to the actual needs, considering the factors such as the availability of raw materials, cost, and difficulty in controlling the reaction conditions, so as to obtain the target product efficiently.

The price of 2-amino-4-trifluoromethyl pyridine in the market is difficult to determine. This is due to many factors that will affect its price, such as the supply and demand of the market, the process of production, the quality of the quality, the quantity purchased, and the channels of supply.
In terms of supply and demand in the market, if there are many demands and few suppliers, the price will increase; on the contrary, if the supply exceeds the demand, the price will decrease. The process of production is also the main reason. If the process is difficult, expensive, and expensive, the price will also be high; if the process is simple and efficient, the cost will decrease, and the price may also be low.
The quality is also related to the price. The price of high-quality goods is often higher than that of ordinary ones. The purchase quantity also has an impact. If the purchase quantity is large, the supplier may give a discount to promote the sale, and the price can be reduced; if the purchase quantity is small, the price may be maintained at the regular price.
The supply channel also controls the price. Direct purchase from the manufacturer is often lower than the purchase price through multi-layer commerce, because it saves the cost of intermediate links.
However, according to the current market conditions, the price of 2-amino-4-trifluoromethylpyridine is between hundreds and thousands of yuan per kilogram. This is only a rough estimate. The market situation changes, and the actual price should be subject to the current inquiry. To know the exact price, it is feasible to ask the suppliers in the chemical raw material market and the chemical mall of the Internet, and inquire about the quantity and price in detail before obtaining a more accurate number.

2-Amino-4-trifluoromethylpyridine is a compound commonly used in organic synthesis. During storage and transportation, many matters must be paid attention to.
When storing, the first ambient temperature. This compound should be stored in a cool place, because high temperature can easily cause its chemical properties to change, or cause decomposition and other adverse conditions. The temperature should be maintained at 2-8 ° C, so as to ensure its stability and reduce the risk of deterioration.
Furthermore, humidity should not be ignored. It should be placed in a dry place to avoid moisture. Because moisture may react with the compound, its purity will be reduced, which will affect subsequent use. A desiccant can be placed in the storage area to maintain a dry environment.
The choice of storage container is also critical. A well-sealed container must be used to prevent it from coming into contact with air. 2-Amino-4-trifluoromethyl pyridine may react with oxygen, carbon dioxide and other components in the air. Sealed containers can prevent such reactions from occurring and ensure quality.
As for transportation, safety protection must be comprehensive. Because it may be dangerous, transportation personnel need to be professionally trained and familiar with its characteristics and emergency treatment methods. Transportation equipment should be stable to prevent damage to the container due to bumps and collisions, resulting in compound leakage.
Packaging must also meet relevant standards. Use appropriate packaging materials to protect the container, and the name, characteristics, hazard warning and other information of the compound should be clearly marked on the packaging, so that all parties can know and handle it properly during transportation.
Transportation route planning should also be prudent. Avoid densely populated areas and environmentally sensitive areas to reduce the harm to the public and the environment in the event of an accident. In this way, 2-amino-4-trifluoromethylpyridine must be properly stored and transported to ensure its quality and safety.
