The chemical synthesis of 3-amino-5-nitrobenzoisothiazole is an important research in the field of organic synthesis. The synthesis path is often started from the parent body of benzoisothiazole, and various chemical reactions are used to introduce amino and nitro functional groups.
The first to bear the brunt is to prepare the parent body of benzoisothiazole. The common method is to use anthranilic acid as the starting material and react with carbon disulfide, base and other reagents to form 2-mercaptobenzamide intermediate. Under appropriate conditions, this intermediate is cyclized to form benzoisothiazole. Specifically, 2-mercaptobenzamide can be obtained when anthranilic acid and carbon disulfide are stirred in an alkaline environment, such as an ethanol solution of sodium ethanol, at a certain temperature (such as 60-80 ° C). Subsequently, the intermediate is heated to 150-200 ° C under the action of dehydrating agents such as sulfuric acid or polyphosphoric acid, and intracyclization occurs to generate benzisothiazole.
After the parent of benzoisothiazole is obtained, the amino group and nitro group are introduced. Nitro groups are introduced, and mixed acids (a mixture of nitric acid and sulfuric acid) are often used as nitrifying reagents. Benzoisothiazole reacts with mixed acids at low temperatures (such as 0-5 ° C), and nitro groups can be introduced at specific positions in the benzene ring. Due to the electron cloud distribution characteristics of the benzoisothiazole ring, the nitro group is mostly substituted at the 5-position. This reaction requires strict temperature control to prevent side reactions such as polynitro substitution.
The method of introducing amino groups is often the reduction of nitrification products. Using 5-nitrobenzoisothiazole as raw material, iron powder and hydrochloric acid system can be used to reduce. In an appropriate solvent (such as ethanol-water mixed solvent), when 5-nitrobenzoisothiazole is co-heated with excess iron powder and hydrochloric acid for a number of refluxes, the nitro group is gradually reduced to an amino group to obtain 3-amino-5-nitrobenzoisothiazole. Catalytic hydrogenation can also be used, using palladium carbon as catalyst and hydrogen as reducing agent to achieve nitro reduction under mild conditions.
In the process of synthesizing 3-amino-5-nitrobenzoisothiazole, the reaction conditions of each step need to be precisely controlled, and the intermediate and product also need to be purified and characterized to ensure the purity and structure of the product. This synthesis method lays the foundation for the application of this compound in the fields of medicine, materials and so on.

3-Amino-5-nitrobenzoisothiazole is a rather special chemical substance. During storage and transportation, many key points need to be paid careful attention.
Bear the brunt. When storing, be sure to find a cool and dry place. This is because it is extremely sensitive to humidity and temperature. High temperature or humid environment may cause chemical reactions to occur, which in turn affects the quality. If the storage environment temperature is too high, or the substance decomposes, releasing harmful gases, which not only endangers the safety of storage facilities, but also poses a threat to the surrounding environment; and if the humidity is too high, it may cause deliquescence and change its physical and chemical properties.
Furthermore, this substance needs to be kept away from fire sources and oxidants. 3-Amino-5-nitrobenzoisothiazole is flammable to a certain extent, and it is easy to burn in case of open flames and hot topics, and may even cause explosions. Contact with oxidizing agents or trigger violent oxidation reactions also poses great dangers.
During transportation, the packaging must be solid and tight. Appropriate packaging materials should be selected to prevent damage to the packaging due to bumps and collisions during transportation, and then leakage. Packaging materials should have good sealing and corrosion resistance to resist the erosion of the substance that may occur on it.
In addition, during transportation, the transportation conditions should be strictly controlled. Avoid mixing with other incompatible substances to prevent mutual reaction. At the same time, transporters also need to be familiar with the characteristics of the substance and emergency treatment methods. In the event of an accident, they can respond quickly and properly to reduce the harm.
In short, the storage and transportation of 3-amino-5-nitrobenzoisothiazole requires attention from various aspects such as the environment, fire source, packaging and transportation conditions, and must not be slack, so as to ensure its safety.
