The synthesis of 7-isoquinoline carboxylic acid is a key issue in the field of organic synthesis. There are many ways to synthesize this compound.
First, isoquinoline can be used as the starting material, through specific reaction conditions, its specific position is modified, and a carboxyl group is introduced. In this process, a suitable nucleophilic substitution reaction is often used to react with a halogen atom or other active group at a specific position on the isoquinoline with a suitable nucleophilic reagent, and then oxidized and other steps to achieve the construction of carboxyl groups.
Second, the isoquinoline ring can be gradually constructed through a multi-step reaction starting from a simple compound containing a structure related to the isoquinoline structure, and carboxyl groups can be introduced at the same time. For example, using a specific aromatic amine and a carbonyl-containing compound as the starting material, through a series of reactions such as condensation and cyclization, the isoquinoline skeleton is first formed, and then the carboxyl group is introduced at the 7 position through appropriate oxidation or other functional group conversion reactions.
Furthermore, the metal-catalyzed reaction is also an effective strategy for the synthesis of 7-isoquinoline carboxylic acids. With the help of transition metal catalysts such as palladium and copper catalyzed cross-coupling reactions, carboxyl-related groups can be precisely introduced at the 7 position of isoquinoline, and then further converted to obtain the target product. < Br >
Synthesis of 7-isoquinoline carboxylic acid requires rational selection of starting materials and reaction paths according to actual conditions, and precise control of reaction conditions and fine experimental operations to obtain this compound efficiently and with high purity.

The price range of 7-isoquinoline carboxylic acid in the market is difficult to say exactly. The price of this chemical often varies due to many factors, such as the quality, the situation of supply and demand, the amount of purchase, and the region and season of sale.
In the past, in books such as "Tiangong Kaiwu", although there is no record of the price of this chemical, the price of many products is discussed in it, and it also varies according to the origin and quality. This principle can be passed to 7-isoquinoline carboxylic acid.
In today's chemical market view, if its quality is high, and in the peak demand season, when the supply is limited, the price may increase. On the contrary, if the quality is ordinary, the market supply exceeds demand, and the price may decrease. And a large purchase is less than a small purchase, and the price per unit may be more favorable.
According to the common price fluctuations of chemical products in the market, the price per gram may be as low as a few yuan. If it is a high-purity, special-purpose product, the price per gram may reach tens of yuan or even higher. However, this is only a rough estimate. The actual price still needs to be consulted in detail with chemical raw material suppliers, chemical reagent sellers and other relevant companies in order to obtain accurate quotations.

7-Isoquinoline carboxylic acid is also a chemical substance. The most important thing for its storage is in a dry place. If this substance encounters moisture or changes, its purity and characteristics will be damaged. Therefore, it is necessary to choose a dry place to avoid the disturbance of water vapor.
Furthermore, temperature is also the key. It should be stored in a cool place, not in a high temperature place. Under high temperature, its chemical structure or changes, resulting in unstable properties. Usually not more than 30 degrees Celsius is appropriate, so that its properties can be kept stable for a long time.
And this substance should be stored with oxidizing and reducing substances. Due to its chemical properties, if it comes into contact with them, or reacts violently, it will cause safety risks. The storage place should also be kept away from fire and heat sources to avoid the risk of fire.
In addition, the storage container should also be carefully selected. Corrosion-resistant materials should be used to prevent chemical reactions between the container and the substance and contaminate its quality. And the container must be well sealed to prevent it from excessive contact with air and oxidation.
In general, the storage of 7-isoquinoline carboxylic acid should be stored in a dry and cool environment, avoiding the danger of water and fire. It should be separated into different types of storage, and the adapter should be selected for close storage, so as to ensure its quality and safety.
