There are several ways to synthesize ethyl 6-methylpyrazolo [1,5-a] pyridine-3-carboxylate (ethyl 6-methylpyrazolo [1,5-a] pyridine-3-carboxylate).
First, it can be prepared by condensation reaction of the corresponding pyrazole and pyridine derivatives. First, take a suitable pyrazole compound. This compound needs to have a specific substituent and react with a reagent containing pyridine structure. Under suitable reaction conditions, such as in a specific organic solvent, add an appropriate catalyst, heat it to a certain temperature, and cause the two to undergo a condensation reaction to form the skeleton structure of the target product.
Second, the cyclization reaction method can also be used. Select a linear precursor with a specific functional group arrangement and undergo intramolecular cyclization to construct the core structure of pyrazolopyridine. The choice of precursor is crucial to ensure that it can occur smoothly under appropriate conditions, such as in the presence of strong acids or bases, or in the presence of specific metal catalysts. After cyclization, the carboxyl group is esterified to introduce the ethyl ester group to obtain ethyl 6 - methylpyrazolo [1,5 - a] pyridine - 3 - carboxylate.
Third, the heterocyclization reaction can also be considered, using nitrogen-containing heterocyclic building blocks to interact with other suitable organic fragments. For example, the nitrogen-containing heterocyclic fragments and compounds with carboxyl groups and other necessary substituents are used in a suitable reaction environment. Through a series of reaction steps such as nucleophilic substitution and electrophilic addition, the structure of the target molecule is gradually established, and finally the purpose of synthesizing ethyl 6-methylpyrazolo [1,5-a] pyridine-3-carboxylate is achieved. Each synthetic method requires fine regulation of reaction conditions to improve yield and product purity.

Ethyl + 6 - methylpyrazolo [1,5 - a] pyridine - 3 - carboxylate, that is, ethyl 6 - methylpyrazolo [1,5 - a] pyridine - 3 - carboxylate, the physical properties are listed below:
View its shape, at room temperature, it is a colorless to light yellow liquid, clear and transparent, like a clear spring, no variegated disturbance, no cloudy state.
Smell its smell, the smell is specific, neither pungent nor disgusting, but its unique smell can be distinguished.
In terms of its melting and boiling point, the melting point is very low, just like winter snow in the warm sun, it is very easy to melt, and in a room temperature environment, it is difficult to condense into a solid state. The boiling point is relatively high, just like a tough person, who needs to be roasted in a hot fire before it turns into a gaseous state and escapes invisibility.
Its solubility, in organic solvents, such as water, can be miscible with many organic solvents, such as ethanol, ether, etc., can be mixed with each other, indistinguishable from each other. However, in water, it is like oil and water, which are difficult to dissolve and distinct.
Above the density, it is slightly lighter than water. If it is placed in water, it is like a light boat floating on the lake, leisurely floating on the water.
Stability is also one of its characteristics. Under normal conditions of room temperature and pressure, its properties are stable, it can be stored for a long time, and it is not easy to change. In the extreme environment of strong acid and alkali, or high temperature and hot topic, the structure is easily damaged when a delicate flower encounters a strong wind, and a chemical reaction occurs and it is transformed into something else.
The approximate physical properties of this ethyl + 6 - methylpyrazolo [1,5 - a] pyridine - 3 - carboxylate can be used for reference by users, so that it can be used in various applications to do its best and avoid its harm.

I think what you are asking is about ethyl + 6 - methylpyrazolo [1,5 - a] pyridine - 3 - carboxylate in the market price range. However, the market changes quickly, and the price is also impermanent. Even if it is contained in "Tiangong Kaiwu", it also changes with time, supply and demand, and origin.
The price of this product is difficult to determine. The price is affected by many factors. First, the difficulty of its preparation is also. If the preparation techniques are complicated, the raw materials required are rare, and the labor force is numerous, the price will be high. Second, the market supply and demand situation. If there are many people who ask for it, and there are few people who supply it, the price will go up; conversely, if the supply exceeds the demand, the price will go down. Furthermore, the origin and quality also affect the price. The best origin comes from the best quality, and the price varies.
According to my guess, it is difficult to determine the exact price without detailed market research. Or at the place where chemical raw materials are traded, consult the dealers to get the latest price. Or look at the chemical information platform, which may have the relevant price dynamics. But this is inconclusive, the market is fickle, and it is necessary to pay attention from time to time to get a more accurate price range.

Ethyl-6-methylpyrazolo [1,5-a] pyridine-3-carboxylic acid ester is an organic compound, which is widely used in chemical industry, pharmaceutical research and development and other fields. However, when using this substance, it is necessary to pay attention to safety matters.
First, protective equipment is essential. This substance may irritate the skin, eyes, and even harm the respiratory tract. Therefore, when operating, wear protective gloves and goggles in front of protective clothing, and if necessary, a gas mask to prevent vapor or dust inhalation.
Second, the operating environment should also be paid attention to. It is suitable to work in a well-ventilated place, and if conditions permit, it is better to operate in a fume hood. This can effectively reduce the accumulation of harmful vapor or dust in the air and reduce the risk of harm.
Third, the method of storage is also exquisite. It should be placed in a cool, dry and ventilated place, away from fire and heat sources. And it must be stored separately from oxidants, acids, alkalis, etc., and should not be mixed to prevent dangerous reactions.
Fourth, emergency treatment, know what to do. If you accidentally come into contact with the skin, you should immediately take off the contaminated clothes and rinse with a lot of flowing water; if it splashes into the eyes, quickly rinse with a lot of water and seek medical attention in time. If you inhale its vapor, quickly go to a fresh place in the air, keep the respiratory tract unobstructed, such as breathing difficulties, give oxygen, stop breathing, immediately perform artificial respiration and seek medical attention.
In conclusion, the use of ethyl-6-methylpyrazolo [1,5-a] pyridine-3-carboxylic acid esters must adhere to strict safety regulations to ensure personal and environmental safety.
