What are the main uses of '4-iodine-3-nitrobenzonitrile '?
The main uses of "4-Flavor-3-Cardamom Astragalus Baishao" are as follows:
This four-flavor medicinal material is compatible and is often used to regulate the spleen and stomach. Cardamom aromatizes and removes moisture, can go through the temperature, can relieve the moisture stagnation of the spleen and stomach, and make the qi of the spleen and stomach smooth; Astragalus has the ability to strengthen the spleen and replenish the middle, raise the yang and subsidence, can enhance the power of the spleen and stomach to transport and transform, and replenish the qi deficiency of the spleen and stomach; Baishao nourishes blood and collects yin, softens the liver and slows down, the liver belongs to wood, and the spleen and stomach belong to soil. Baishao can soften the liver to prevent the liver wood from multiplying the spleen soil. At the same time, it is associated with Astragalus, one supplement and one astringent, and
It is also effective in the regulation of qi and blood. Astragalus nourishes vitality, qi can generate blood, and requires medicine for nourishing qi; Baishao nourishes blood and camp, and the two cooperate to nourish qi and nourish blood. It has the effect of improving people with insufficient qi and blood, such as yellowing complexion, fatigue, dizziness, etc.
It plays a role in the coordination of the relationship between the liver and the spleen. The liver governs the drainage, and the spleen governs the transportation and transformation, and the two are related to each other. Baishao softens the liver, cardamom, and astragalus strengthen the spleen, so that the drainage of the liver is normal, and the transportation and transformation of the spleen are orderly. It has a conditioning effect on chest and flank swelling, abdominal pain and diarrhea caused by liver and spleen imbalance.
It is also often used in gynecological diseases such as irregular menstruation in women. Baishao nourishes blood and regulates menstruation, and Astragalus replenishes qi to help blood flow. The combination of the two can play a certain role in conditioning if women have menstrual cycle disorders and abnormal menstruation due to lack of qi and blood, liver and spleen disorders.
To sum up, "4-flavor-3-cardamom Astragalus Baishao" is reasonably compatible according to different diseases and constitutions, and plays an important medicinal value in spleen and stomach conditioning, qi and blood nourishment, liver and spleen coordination, and some gynecological diseases.
What is the synthesis method of '4-iodine-3-nitrobenzonitrile '?
The synthesis method of "4-question-3-caseyl glycine peptide" is as follows:
To make caseyl glycine peptide, you can follow the method of condensation reaction. First take caseyl and glycine, which are the base materials for synthesis. The caseyl one is rich in a special chemical structure and has a specific activity check point; although glycine is simple, it is indispensable in the construction of peptides.
In order to make the two condensate, suitable reaction conditions are often required. Choose an appropriate solvent, which needs to be able to dissolve casyl and glycine without adverse interference to the reaction, such as dimethylformamide, which is often preferred due to its good solubility and relative chemical inertness.
Introducing a condensing agent is also key. Commonly used condensing agents such as dicyclohexylcarbodiimide (DCC) can activate carboxyl groups to promote the condensation reaction between the carboxyl group of casyl and the amino group of glycine. DCC can interact with carboxyl groups to form active intermediates, reduce the activation energy of the reaction, and make the amino group easy to attack, thereby forming peptide bonds.
During the reaction process, it is necessary to fine-tune the temperature and pH. If the temperature is too high, it may cause side reactions to breed and destroy the structure of the target product; if the temperature is too low, the reaction rate will be slow and take too long. Generally speaking, the reaction temperature is usually controlled in the range of room temperature to moderate heating, between about 20-50 degrees Celsius. As for the pH, the buffer solution can be maintained at a specific pH range to facilitate the smooth progress of the reaction. Usually, the pH is about 6-8.
After the reaction is completed, the product may contain impurities and needs to be separated and purified. Column chromatography can be used to separate the target product from the impurities according to the difference in the distribution coefficient between the stationary phase and the mobile phase of different substances. Silica gel column is commonly used, select the appropriate eluent, so that the pure precipitation of tyroglycine peptide, the final synthetic product of this peptide.
What is the market price of '4-Iodine-3-nitrobenzonitrile '?
The market price of "4-Question-3-Tyroglycine Peptide" is difficult to determine. Covering this "4-Question-3-Tyroglycine Peptide", as far as I know, it is not possible to describe its exact market situation in detail in the ancient books. And the business affairs of the world are changing rapidly, and the price is often different for many reasons.
First, the scarcity of the source of production is related to the market price. If the source of this product is abundant and the supply is abundant, the price may tend to be flat; if its production is rare, the collection is difficult, and the supply is scarce, the price will be expensive. For example, the silk woven by the mackerel people in the South China Sea, because its output is rare, the price is high and difficult to climb.
Second, the amount of purchase also affects the price. If everyone is competing for this "4-question-3-caseoglycine peptide", the demand is greater than the supply, and the price will rise; if there are few people asking for it, the supply will exceed the demand, and the price will inevitably drop. Just like the good horses of the Western Regions in the past, the countries of the Central Plains competed to buy it, and the price was high.
Third, the difficulty of refining is involved. If the method of refining this thing is simple, the cost is low, and the price is not high; if the refining technique is complicated, it is time-consuming and expensive, and the price will be high. Like the refining of elixir, the process is complicated, and there are many rare materials required, so the price is incomparably high.
Fourth, the comparison of similar products in the market also affects their price. If there are similar products, and they are cheap and high quality, people may tend to them, and the price of this "4-question-3-caseylglycine peptide" may be suppressed; if there is no similar comparison, it is unique in the market, and the price may be higher.
Although the exact price of "4-question-3-caseylglycine peptide" is not known in detail, it is difficult to determine whether the market price is in a dynamic state due to factors such as source, purchase, refining, and similar comparison.
What are the precautions for "4-iodine-3-nitrobenzonitrile" in storage and transportation?
"4-Question-3-testosterone-based estradiol", be sure to pay attention to everything during storage and transportation. This medicine has special properties, and when stored, the first environment is heavy. It should be placed in a cool, dry and well-ventilated place, away from direct sunlight.
