5-Amino-2 - (p-aminophenyl) benzimidazole sulfonamide, also known as sulfadiazine, is an important member of sulfonamide antibacterial drugs. Its main uses are as follows:
First, it is used to treat bacterial infections. This drug has antibacterial activity against many Gram-positive and Gram-negative bacteria, such as Streptococcus pneumoniae, Haemolytic Streptococcus, Neisseria meningitidis, Escherichia coli, Proteus, etc. It can be used for many infections caused by these bacteria, such as respiratory tract infections, which can relieve pneumonia, bronchitis, etc.; urinary tract infections, which can help relieve symptoms such as urethritis and cystitis; intestinal infections, which can deal with dysentery, enteritis and other diseases.
Second, for epidemic cerebrospinal meningitis caused by Neisseria meningitidis, sulfadiazine is a key therapeutic drug. The drug easily penetrates the blood-brain barrier and can reach an effective antibacterial concentration in the cerebrospinal fluid, which is of great significance for controlling the disease and reducing the mortality rate.
Third, it is also used in the prevention of epidemic cerebrospinal meningitis. During the epidemic period, for susceptible people, especially close contacts, oral sulfadiazine can be taken for prevention to reduce the chance of infection.
Fourth, some specific infections, such as combined use with trimethoprim, can enhance the antibacterial effect, broaden the antibacterial spectrum, and be used to treat infections caused by some complex or drug-resistant bacteria.
If the use of this medicine is recorded in ancient Chinese in Tiangong Kaiwu, or as follows: "5-Amino-2 - (p-aminophenyl) benzimidazole sulfonamide is a sulfonamide antibacterial drug. It can treat all kinds of bacteria, and Gram's yin and yang bacteria can be made. Such as Streptococcus pneumoniae, hemolytic streptococcus, Neisseria meningitidis, Escherichia coli, Proteus and other diseases, respiratory infections, such as pneumonia, bronchitis; urinary tract diseases, such as urethritis, cystitis; intestinal diseases, such as dysentery, enteritis, etc., can be used. And in the case of meningococcal meningitis caused by Neisseria meningitidis, this drug is particularly severe, it can penetrate the blood-brain barrier, obtain effective antibacterial concentration in the cerebrospinal fluid, control the disease and reduce the mortality rate. During the epidemic of meningitis, people who are susceptible, especially those who are in close contact, can take this drug orally to predict and reduce the chance of contracting the disease. And when applied in combination with methoxybenzidine, it can increase the antibacterial effect, expand the antibacterial spectrum, and treat various infections caused by complex or drug-resistant bacteria.

To prepare 5-amino-2 - (p-aminophenyl) aniline and nitramine, the method is as follows:
Take the appropriate raw materials first, and carefully select them to ensure that the texture is pure and the quality is high. This is the foundation of synthesis. Take p-nitroaniline as the starting material and make it undergo a specific chemical reaction under suitable reaction conditions.
In the reactor, put an appropriate amount of p-nitroaniline, add specific reagents and solvents, and control the temperature, pressure and reaction time. If under mild heating conditions, stir slowly to make the reactants fully contact and react. Using ingenious chemical means, the nitro group of p-nitroaniline is gradually converted, or the nitro group is converted into an amino group by reduction reaction. This step requires careful operation. Due to the delicate reaction process, a slight difference in the pool will affect the purity and yield of the product.
After the first step of the reaction is completed, the resulting product is carefully treated to remove impurities and purify. Then, based on this product, another key reaction step is introduced. Combine it with a specific aniline derivative, and under the action of a suitable catalyst, promote the condensation or substitution of the two. When reacting, pay close attention to the reaction phenomenon and fine-tune the reaction parameters according to the actual situation to achieve the best reaction effect.
After the reaction is completed, the final product is carefully separated and purified. Methods such as recrystallization and column chromatography can be used to remove residual impurities and unreacted raw materials to obtain high-purity 5-amino-2 - (p-aminophenyl) aniline and nitramine. The entire synthesis process requires the patience of craftsmen and the ingenuity of wise people. Every step is about success or failure. Only by doing it carefully can you get a good product.

5-Hydroxy-2 - (p-hydroxyphenyl) benzofuranone must be paid attention to during storage and transportation.
First environmental conditions. This substance is quite sensitive to temperature and humidity. When storing, it should be placed in a cool, dry and well-ventilated place. If the ambient temperature is too high, it may cause its chemical properties to be unstable and accelerate decomposition and deterioration; if the humidity is too high, it is easy to cause deliquescence and affect the quality. Therefore, the warehouse temperature should be controlled within the [suitable temperature range], and the relative humidity should be maintained within the [suitable humidity range].
During transportation, it is also necessary to ensure that the temperature is stable and avoid extreme temperature fluctuations. Temperature-controlled transportation equipment, such as refrigerated trucks, can be used to maintain its stability.
This is the second packaging material. Due to its certain chemical activity, packaging materials must be carefully selected. Materials that can effectively block air, moisture and light, such as aluminum foil bags, glass bottles, etc., should be used, and the seal must be tight. This is to prevent reactions with external substances, especially to avoid contact with oxidizing or reducing substances, in order to prevent chemical reactions from triggering the failure of the substance.
Furthermore, the handling process needs to be careful. 5-Hydroxy-2 - (p-hydroxyphenyl) benzofuranone may be fragile in texture, and rough handling can easily cause package damage. Once the packaging is damaged, external factors can easily intrude and affect its quality. Therefore, it should be handled with care to prevent collisions and falls.
In addition, whether it is storage or transportation, it should be kept away from fire sources, heat sources and flammable and explosive items. Although this substance is not a typical flammable and explosive substance, it may still pose risks under certain conditions. At the same time, it is necessary to strictly follow relevant regulations and safety standards, and make labels and records for traceability and management.
