3-Amino-1,2-benzoisothiazole, this material has unique properties and is of great value for investigation. It is a crystalline powder with a light yellow color and fine appearance. Under normal temperature and pressure, it is quite stable, just like a calm person, and is not easily disturbed by the outside world.
On its melting point, it is about 153-155 ° C. When the temperature reaches this point, it is like ice when it is warm and begins to change shape quietly. Its solubility also has characteristics. It is slightly soluble in water, just like a light boat on the surface of a lake, and it is difficult to melt in large quantities. However, it can be better dissolved in organic solvents, such as ethanol and acetone, like a fish entering a river and blending freely.
Its chemical properties are active, and the existence of amino groups gives it the ability to form salts with acids, just like yin and yang attract each other and combine with each other. And due to the structure of benzoisothiazole, it has a certain reactivity and can participate in various organic reactions. In the field of chemical synthesis, it is like a delicate key, which can open the door of many reactions, and has a wide range of uses. It can play an important role in the creation of medicine, pesticides, etc., contributing to the development of the industry.

The synthesis method of 3-amino-1,2-benzoisothiazole has been known for a long time. There are many methods, and each has its own ingenuity.
First, anthranilic acid is used as the starting material and prepared by multi-step reaction. First, the anthranilic acid is reacted with thiophosphorus. In this step, attention should be paid to the control of the reaction conditions. Temperature and pH will affect the product. Thiophosphorus activity is quite high, and the reaction should be carried out at low temperature and protected by inert gas to obtain the desired intermediate. The intermediate is then cyclized. This process requires specific catalysts, such as some metal salts, to be converted into 3-amino-1,2-benzoisothiazole. < Br >
Second, o-nitrotoluene is used as the starting material. First, o-nitrotoluene is oxidized to obtain o-nitrobenzoic acid. This oxidation reaction conditions are harsh, and strong oxidizing agents and suitable reaction environments are required. Subsequently, o-nitrobenzoic acid is reduced to o-aminobenzoic acid, and then reacts with thiophosphorus as before, and then cyclizes through intermediates to obtain the target product.
Third, 2-mercaptoaniline is used as the raw material. 2-mercaptoaniline reacts with halogenated acetate to form a sulfide-containing structural intermediate. After that, the intermediate is cyclized under alkaline conditions. The strength of alkalinity and reaction time have a great influence on the cyclization effect. After this step, 3-amino-1,2-benzoisothiazole can be prepared.
All synthesis methods have advantages and disadvantages. The choice of starting materials, the difficulty of reaction conditions, the purity and yield of the product are all factors to consider. Synthesizers should weigh the advantages and disadvantages according to actual needs, and choose the appropriate method.

The price range of 3-amino-1,2-benzisothiazole in the market is difficult to say exactly. The price of this compound is determined by many factors, just like a silk network that affects the whole body.
The first to bear the brunt is the price of raw materials. The synthesis of this compound, the cost of raw materials acquisition, is as high as the cornerstone of a tall building. If raw materials are scarce, the price will soar, causing the price of finished products to rise; on the contrary, if raw materials are abundant, the price will be stable.
Furthermore, the production process is also crucial. Exquisite and advanced technology can increase output efficiency, reduce cost consumption, and its price may be close to the people; if the process is cumbersome and backward, it consumes a lot of manpower and material resources, and the price is difficult to drop.
The state of supply and demand in the market is also the key. Demand exceeds supply, just like thirsty people meet sweet, merchants raise their prices; oversupply, such as those who stock goods in the market and ask less, the price may be reduced to sell.
There is a quality factor. Those with high quality are favored in high-end fields such as medicine and fine chemicals, and the price is high; those with poor quality are only suitable for places with loose requirements, and the price must be low. < Br >
From this perspective, the market price of 3-amino-1,2-benzoisothiazole often hovers between tens of yuan per kilogram and hundreds of yuan per kilogram. However, this is only an approximate number, and the actual price needs to be carefully studied according to the current market conditions.
