In industrial production, it can be used as an intermediate in organic synthesis, participating in the synthesis process of many complex organic compounds, greatly enriching the types and properties of organic compounds, and promoting the vigorous development of the chemical industry. Overall, 2-chloro-3-methylpyridine, with its high purity, plays an irreplaceable role in many fields and is of great significance to the progress of various industries.

2-Chloro-3-methylpyridine, with a purity of 98% and 25%. This is a chemical substance, and its physical properties are quite important. Looking at its appearance, under normal temperature and pressure, it is mostly a colorless to light yellow transparent liquid, like warm amber, quiet and flowing light. Smell it, it has a special pungent smell, just like a hidden and sharp signal, reminding everyone of its unique chemistry.
Its boiling point is related to the state transformation of a substance under specific conditions, about a certain temperature range, which allows the molecule to get rid of the liquid phase and Pentium into a gas phase. The melting point determines the critical temperature at which it converts from a solid state to a liquid state, like a life trajectory node of a substance.
Solubility is also a key property. In organic solvents, such as ethanol, ether, etc., it is like a wanderer returning home, and it can dissolve well with each other, just like a fish entering water and blending freely. However, in water, its solubility is relatively limited, and the two seem to have a natural barrier, and can only be partially mixed.
Compared with water, its density has its unique value. In a container, when it encounters water, it can either float on water or sink underwater with its own density characteristics, showing its unique physical nature.
These physical properties are as important as cornerstones in many fields such as chemical synthesis and industrial applications. They affect the way and efficiency of its participation in the reaction, and also determine the actual operation methods such as storage and transportation.

The chemical properties of 2-chloro-3-methylpyridine, when the content reaches 98%, are usually quite stable. The appearance of this substance is often colorless to pale yellow liquid, and it can maintain a relatively stable state under conventional environmental conditions.
From the perspective of chemical structure, the presence of pyridine rings endows it with certain aromatic properties and conjugation stability. Although the substitution of chlorine atoms and methyl groups has an impact on the electron cloud distribution of pyridine rings, its chemical properties have not been drastically changed. At room temperature and pressure, without the intervention of specific chemical reaction conditions, 2-chloro-3-methylpyridine can be stored for a long time without significant deterioration.
However, its stability is not absolute. In case of strong oxidants, chlorine atoms may be oxidized, causing their structure to change. In case of high temperature or open flame, there is also a risk of combustion or even explosion, because it is an organic compound and flammable. And under specific catalysts and suitable reaction conditions, it can participate in many chemical reactions, such as nucleophilic substitution reaction, chlorine atoms can be replaced by other nucleophilic reagents.
In general, under conventional storage and use conditions, the chemical properties of 2-chloro-3-methylpyridine are relatively stable, but chemical safety regulations must be followed during operation to avoid potential hazards.

2-Chloro-3-methylpyridine, with a content of 98%, there are several common methods for its preparation.
First, 3-methylpyridine is used as the starting material. First, 3-methylpyridine is chlorinated with appropriate chlorine reagents, such as chlorine gas or thionyl chloride, under specific reaction conditions. When chlorine is used as the chlorine reagent, it is often necessary to use light or the presence of an initiator to promote the smooth occurrence of the reaction. The effect of this light or initiator is to generate chlorine radicals, which then react with specific positions on the pyridine ring of 3-methylpyridine to form 2-chloro-3-methylpyridine. At the time of reaction, factors such as temperature, reaction time, and the proportion of reactants all have a significant impact on the yield and selectivity of the reaction.
Second, through the synthesis path of pyridine derivatives. The structure of the pyridine ring can be constructed first, and methyl and chlorine atoms can be introduced at suitable positions during the construction process. For example, with a specific nitrogen-containing and carbon-containing raw material, a series of organic reactions such as condensation and cyclization are gradually formed to form a pyridine ring, and during the reaction process, the reaction conditions are precisely controlled, so that the methyl and chlorine atoms are respectively connected to the 3 and 2 positions of the pyridine ring, so as to achieve the purpose of preparing 2-chloro-3-methylpyridine. Although this method is slightly complicated, the position of the substituent on the pyridine ring can be precisely controlled.
Third, there are also methods of catalyzing with transition metals. Select suitable transition metal catalysts, such as palladium, copper and other metal complexes, and cooperate with specific ligands to promote the coupling reaction between halogenated hydrocarbons and 3-methylpyridine derivatives. In this reaction system, the chlorine atoms carried by halogenated hydrocarbons can be coupled with specific positions of 3-methylpyridine under the action of transition metal catalysts to generate the target product 2-chloro-3-methylpyridine. This method has many advantages such as relatively mild reaction conditions and high selectivity.
Different preparation methods have their own advantages and disadvantages. In actual production, the appropriate production method needs to be carefully selected according to specific needs, cost considerations, and requirements for product purity.

It is difficult to determine the market price range of 2-chloro-3-methylpyridine with a purity of 98%. The price of the market often changes for many reasons.
Looking at the market of chemical materials in the past, first, the price of raw materials is very critical. If all the raw materials required to generate 2-chloro-3-methylpyridine are changed in origin and output, or due to weather or personnel reasons, the raw materials are scarce, and the price will rise, and the price of this product will also rise. On the contrary, if the raw materials are abundant, the price may drop.
Second, the trend of supply and demand determines the price. If the demand for 2-chloro-3-methylpyridine is greatly increased by many companies and workshops in a certain field at a certain time, and the output is limited, the supply is in short supply, and the price is high; if the demand is weak, the output is excessive, and the supply exceeds the demand, the price will fall.
Third, changes in the process also have an impact. The new and exquisite process can reduce consumption and improve production, reduce its cost, and the price may be reduced; however, if the process encounters difficulties, the cost will increase, and the price will rise again.
Fourth, the cost of business travel, such as storage, transportation, etc., cannot be ignored. The distance between the place of origin and the place of sale, and the convenience of transportation, are all related to the cost of transportation. When warehousing, if special methods are required, the cost will also increase, which will cause the price of the product to fluctuate.
Similar to chemicals in the past, due to the above factors, the price fluctuates greatly. Or in a certain season, the price is tens of gold per kilogram; or in other times, due to the abundance of raw materials and a slight decrease in demand, the price drops to twenty or thirty gold per kilogram. Therefore, for 2-chloro-3-methylpyridine with 98% purity, the market price may fluctuate between twenty gold and eighty gold per kilogram, but this is only an approximate number. The truth still needs to be carefully examined in the current market situation.
