Second and melting point, the melting point of this substance is quite high, about 240-244 ℃. The melting point is the critical temperature at which the substance changes from solid to liquid state. This higher melting point indicates that the compound has strong intermolecular forces, relatively stable structure, and requires higher energy to cause its morphological transformation.
Besides solubility, 2-amino-6-nitrobenzothiazole is slightly soluble in water. Water is the source of all things, and the solvent of many substances. However, this compound has limited solubility in water, because its molecular structure contains hydrophobic groups, and its affinity with water molecules is weak, so it is difficult to dissolve. However, it is soluble in some organic solvents, such as dimethyl sulfoxide (DMSO), N, N-dimethylformamide (DMF), etc. The molecular structure of this organic solvent is similar to that of this compound, and it can be dissolved according to the principle of "similar and soluble".
And stability, 2-amino-6-nitrobenzothiazole is quite stable under general conditions, but when it encounters strong oxidizing agents, strong acids, strong bases, etc., it can undergo chemical reactions. The amino group and nitro group in its molecule are reactive, and when it encounters specific reagents, it can cause structural changes, triggering substitution, redox and other reactions.
In addition, the substance has a certain odor, but its taste is not strong and there is no special irritation. Its density and other physical properties also have certain similarities with similar organic compounds, but the specific value needs to be determined by precise experiments to confirm its details. All kinds of physical properties are of important reference value in the fields of chemical synthesis, analysis and testing, application development, etc., which help researchers to clarify their characteristics and lay the foundation for related work.

The chemical synthesis method of 2-amino-6-nitrobenzothiazole, as described in past books, is as follows.
Usually 2-aminobenzothiazole is used as the starting material. First take an appropriate amount of 2-aminobenzothiazole, place it in a suitable reaction vessel, and add an appropriate amount of solvent, such as glacial acetic acid, concentrated sulfuric acid, etc., which can create a suitable environment for subsequent reactions.
Then, slowly add nitrifying reagents, such as concentrated nitric acid and concentrated sulfuric acid mixed in a specific ratio. It is necessary to be cautious when adding time. Due to the violent nature of nitrification reactions, it is crucial to control the drip acceleration and reaction temperature. Generally, it is maintained at a low temperature, such as between 0 and 5 ° C, to prevent side reactions from breeding. After adding, let it continue to stir the reaction at low temperature for a period of time, so that the nitrifying reagent can fully interact with 2-aminobenzothiazole.
During the reaction, regular sampling is used to monitor the progress of the reaction. The degree of reaction can be observed by means of thin-layer chromatography. When the reaction reaches the expected level, the reaction liquid is slowly poured into ice water to precipitate the product. Subsequently, the precipitated solid is collected by suction filtration, and then washed with water or organic solvent several times to remove impurities.
The obtained crude product often needs to be further purified. The method of recrystallization can be used to select suitable solvents, such as ethanol, ethyl acetate, etc., heat to dissolve the crude product, filter while hot to remove insoluble impurities, cool the filtrate, recrystallize the product and precipitate it, and then filter and dry it to obtain pure 2-amino-6-nitrobenzothiazole.
Another method is to use o-nitroaniline as the starting material and react with ammonium thiocyanate to obtain 2-amino-6-nitrobenzothiourea first, and then cyclize to obtain the target product. In this way, it is also necessary to pay attention to the control of reaction conditions at each step, such as reaction temperature, reaction time and the proportion of reactants, etc., to obtain satisfactory yield and purity.

2-Amino-6-nitrobenzothiazole is also a chemical substance. When storing and transporting, be sure to pay attention to many matters.
Its nature may be dangerous. When storing, first find a cool, dry and well-ventilated place. Do not place it in direct sunlight to prevent excessive temperature from changing its properties or even causing danger. The temperature and humidity of the warehouse should also be properly regulated and maintained within an appropriate range.
In addition, this substance may react chemically with other substances, so it must be stored separately from oxidants, acids, bases, etc., and should not be mixed to avoid accidents due to interaction.
When transporting, care must also be taken. The means of transportation used must be clean, dry, and free of other chemical residues to prevent contamination. During transportation, ensure that the container is well sealed to avoid leakage. The escort personnel must be well versed in the characteristics of this substance and emergency treatment methods to prepare for emergencies.
If the transportation encounters high temperature weather, the necessary cooling measures should be taken to prevent the danger caused by the increase in temperature. During loading and unloading, the operator should also handle it with care and do not operate brutally to prevent the container from being damaged and causing leakage accidents. In this way, the safety of 2-amino-6-nitrobenzothiazole during storage and transportation must be ensured.

2-Amino-6-nitrobenzothiazole, the price of this product in the market is difficult to be fixed, and its price often changes due to many reasons. Looking at the market conditions of the past, the price of this material varies depending on the state of supply and demand, the difference in quality, and the difference in production.
If the demand in the market exceeds the supply, the price may be raised. There are many buyers and there are few goods, and sellers often offer it at a high price in order to make a big profit. If the supply exceeds the demand, the price may drop. If merchants want to sell their goods quickly, they must reduce the price to attract buyers.
Furthermore, the quality of the quality of the product has a great impact on the price. Those who are of high quality, the price is always high, because they can be used for high-seeking industries, and the efficiency is good and widely used. Those who are of poor quality, the price is low, and it is only suitable for less and less travel.
The place where the source of production is also related to its price. If the source is close and easy to transport, the cost will be saved and the price will be appropriate. If the source is far away, plus the freight, the price will be higher.
The traces of the past, the price of this 2-amino-6-nitrobenzothiazole is between tens and hundreds of yuan per kilogram. However, this is only an approximate number. The current price situation is difficult to determine. Those who enter the market should carefully observe the current situation of the city and consult many companies before they can obtain a more accurate price.
