The method of preparing N- (4-aminobenzoyl) - 2-amino-8-naphthol-3,6-disulfonic acid has been explored by many families in the past. The first method is to use 4-aminobenzoic acid and 2-amino-8-naphthol-3,6-disulfonic acid as the starting materials, and to obtain it by condensation under a suitable reaction environment. Among them, the choice of solvent, the control of temperature, and the duration of the reaction are all key. If the solvent is not good, the reaction may be difficult; if the temperature is not suitable, the purity and yield of the product will be affected; if the time is improper, the reaction may be incomplete, or excessive, and the product will be damaged.
Second, 4-aminobenzoic acid is first acylated to form an active acylated intermediate, and then interacts with 2-amino-8-naphthol-3,6-disulfonic acid. When acylating, the property and dosage of acylating reagents, the availability and dosage of catalysts, all affect the reaction. Then it is necessary to fine-tune the reaction conditions with naphthol derivatives in order to obtain satisfactory results.
There are other methods for preparing, or first modifying a group of naphthol derivatives to increase its reactivity, and then reacting with 4-aminobenzoic acid related substances; or changing the order of the reaction, adding additives, etc., to obtain the best method. However, each method has its own advantages and disadvantages. It is necessary to consider the availability of raw materials, the cost, and the quality and quantity of products according to actual needs, and choose them carefully to achieve the best preparation conditions.

N- (4-aminobenzoyl) - 2-amino-8-naphthol-3,6-disulfonic acid, when using this substance, many matters need to be paid attention to.
