The synthesis method of 1H-pyrazolo [3,4-c] pyridine-5-chlorine, although the synthesis of such specific compounds is not directly recorded in the ancient book "Tiangong Kaiwu", the chemical process ideas contained in it may be enlightening for its synthesis.
Looking at "Tiangong Kaiwu", the preparation of various substances follows a step-by-step and exquisite preparation method. To synthesize this compound, you can start from the basic raw materials first. The compound containing the pyridine structure is used as the initial substrate, and the pyridine ring has stable aromatic properties. Chlorine atoms can be introduced into the pyridine ring at the appropriate position by halogenation reaction. This step requires precise control of the reaction conditions, such as temperature, reaction time, and the amount of halogenated reagents. If the temperature is too high, it may cause excessive halogenation or damage to the structure of the pyridine ring; if the temperature is too low, the reaction rate will be slow and the yield will be poor.
As for the construction of the pyrazole ring, the nitrogen-containing compound and an appropriate carbon source can be selected according to the idea of constructing a complex structure in Tiangong Kaiwu. Take advantage of the nucleophilicity of the nitrogen atom in the nitrogen-containing compound to condensate with the carbon source. In the reaction, a suitable catalyst may be required to promote the reaction, and the influence of the catalyst on the selectivity of the reaction needs to be considered, and the pyrazole ring should be constructed at a specific position of the pyridine ring to generate the target pyrazolo [3,4-c] pyridine structure. In the
reaction process, each step needs to be carefully monitored and regulated. "Tiangongkai" also emphasizes the control of the process. Modern analytical methods, such as thin-layer chromatography, nuclear magnetic resonance, etc., can be used to monitor the reaction process and product purity. After each step of the reaction, properly handle the reaction mixture, separate and purify the product, remove impurities, and provide pure raw materials for the next reaction. In this way, following scientific and reasonable steps and referring to the process ideas of "Tiangongkai", an effective synthesis of 1H-pyrazolo [3,4-c] pyridine-5-chloride can be achieved.

I don't know if 1H - pyrazolo [3,4 - c] pyridine, 5 - chloro - is in the market price range. This is a more professional chemical substance, and its price is determined by many factors. First, the purity is extremely critical, and the price of high purity must be higher than that of low purity. Second, the difficulty of the production process is different. If the process is complicated and the cost rises, the price is also high. Third, the market supply and demand situation has a great impact. If demand is strong and supply is scarce, the price will rise; conversely, if supply exceeds demand, the price may fall. Fourth, different suppliers have different pricing strategies, which also lead to differences in prices.
