What are the synthesis methods of 7-anilino-4-hydroxy-2-naphthalenesulfonic acid?

There are several ways to synthesize tannic acid. One is to use gallic acid and pyrogallic acid as raw materials and obtain it through a condensation reaction. Under appropriate conditions, the two interact, condensation occurs between molecules, and the structure of tannic acid is formed.
There is also a method of chemical modification starting with natural plant extracts. Many plants, such as gallnut, are rich in materials that can be converted. After extraction, separation and other steps, an extract rich in related ingredients is obtained, and then its structure is changed by chemical means to convert it into tannic acid. This method is based on natural materials and has a more environmentally friendly meaning. However, the process is complicated and requires fine operation to control the purity and quality of the product.
Furthermore, the approach of organic synthesis chemistry can be used, starting with the basic organic compound. First construct a suitable carbon skeleton, and then introduce the corresponding functional groups according to the structural characteristics of tannic acid. Although the starting materials are easily available in this approach, the reaction steps may be lengthy, and precise control of reaction conditions and purification of intermediates are required to ensure the correctness and high purity of the final product.
Each method has its advantages and disadvantages. The shrinkage method using gallic acid as raw materials is relatively direct, but the cost and source of raw materials may be limited. Based on the method of natural extracts, it has a natural basis, but the extraction and transformation process requires effort. Although the method of organic synthesis chemistry can accurately construct the structure, the steps are cumbersome and costly or high. When choosing a method, we should comprehensively consider the availability of raw materials, cost, process difficulty, product quality and other factors, and weigh and choose to achieve the best condition of tannic acid synthesis.
