2-iodo-6-methyl-4-nitro-aniline

What is the main use of 2-% question-6-A-stem-4-wolfberry silver warp? There may be some ambiguities in the formulation of this question. It is speculated that the "2-% question" may be marked with the serial number. The concept of "A-stem" is unclear. The common "wolfberry silver warp" may be a combination of "silver warp" and "wolfberry". In the relevant records and traditional cognition of "Tiangong Kaiwu", the answer in ancient Chinese form for you is as follows:
Silver warp, its flowers and leaves are cold in nature, and have the effect of clearing away heat and detoxifying and evacuating wind and heat. In medical medicine, it is often used to treat exogenous wind and heat diseases, such as fever, headache, and sore throat. It can be used in combination according to the symptoms. It can dissipate the evil of wind and heat, relieve the stagnation of heat and poison in the body, and is a commonly used material for medical treatment of such diseases.
Lycium barbarum, the fruit is sweet in taste and flat in nature. Into the liver and kidney meridians. It has the functions of nourishing the liver and kidney, and improving the essence and eyesight. It is often used for the syndrome of yin deficiency of the liver and kidney. If people have soreness at the waist and knee, dizziness, and dizziness in vision, wolfberry is often used as medicine or dietary therapy. In dietary therapy, it can be cooked with various ingredients, such as chicken and ribs, which can not only increase the nutrition of the diet, but also nourish the body. For medicinal use, it is often combined with other medicines to treat various diseases of liver and kidney deficiency. Or single-flavor chewing, it also has the power of nourishing, and is a good product for health care and disease treatment.

There are several methods for the synthesis of 2-% problem-6-amino-4-pyrimidine aminobenzoic acid. Although the synthesis method of such compounds is not detailed in Tiangong Kaiwu, there are also many chemical processes and synthesis wisdom in ancient times, which can be used for analogy and derivation.
One of them may be the method of natural extraction and then transformation. It can be seen from ancient herbal books that many plants and minerals contain various organic and inorganic components. If you find natural substances with similar structures, you can use the methods of ancient extraction, such as water leaching, wine soaking, distillation, etc., to obtain crude extracts. Then purify by precipitation, crystallization, etc., to obtain relatively pure substances. According to the principle of chemical transformation, 6-amino-4-pyrimidine aminobenzoic acid can be obtained through modification and derivatization steps. For example, in ancient alchemy, natural ores were often used as raw materials and their chemical composition was changed through multi-step processing.
Second, it can simulate the ancient concept of organic synthesis. Although there was no modern precise theory in ancient times, some reaction laws were also explored in practice. For example, common carboxylic acids and amines were used as starting materials. Although carboxylic acids and amines were not clearly defined in ancient times, carboxylic acids could be obtained from hydrolysis of animal and vegetable oils, and ammonia components could be obtained from degradation of nitrogen-containing vegetable proteins. The condensation reaction occurs between the two. Although this reaction does not have the precise catalysis of modern catalysts, it can be promoted by high temperature, long-term heating and other conditions. Some natural alkaline substances, such as plant ash, may need to be added to the reaction to promote the equilibrium movement of the reaction.
Third, learn from the ancient fermentation process. Fermentation can produce a variety of organic compounds with complex structures. Special strains can be screened to create a specific fermentation environment, so that microorganisms can produce intermediates containing target structures during metabolism. After separation, purification, and further chemical modification, 6-amino-4-pyrimidinaminobenzoic acid is finally obtained. The ancient winemaking and vinegar brewing processes are all examples of clever use of microbial metabolism, which can be used for reference.
Although "Tiangong Kaiwu" does not contain a specific method for the synthesis of this compound, combined with the wisdom of ancient chemical processes, the above methods may be feasible, and the way of synthesis can be explored in ancient records and practical experience.

2-%-6-amino-4-pyrimidine aminobenzoic acid is a special compound, which is widely used in the fields of medicine and pesticides. It has many unique chemical properties, which are described in detail today.
In this compound, the amino group is connected to the pyrimidine ring and benzoic acid structure, resulting in an acid-base amphoteric. Because the amino group is alkaline, it can form salts with acids. When encountering strong acids such as hydrochloric acid, the nitrogen atom in the amino group will combine with the hydrogen ion in the acid to form a corresponding ammonium salt. This property is used in pharmaceutical preparations to increase its solubility and stability, which facilitates drug absorption.
At the same time, the carboxyl group of the benzoic acid part of the compound is acidic and can neutralize with bases. In case of strong bases such as sodium hydroxide, the carboxyl group will react with hydroxide ions to form carboxylic salts and water.

The medicine of the two flavors of the husband, the six are the first, and the four are the children. It is hidden in the scarcity, and it is on the way. In the meantime, pay attention to all things.
When you hide it, the first thing to pay attention to is its quality. The first one is tough, like the solid of gold and stone. You should look for its flawless one to prevent it from corroding. The child is a warm and moist body, like the luster of pearls and jade, do not let it dry. Both should be protected from water and fire, which are ruthless and can destroy its quality. Keep it in a dry place in the shade, protected from direct sunlight, to prevent its color from changing and flavor.
Furthermore, the storage utensils must also be suitable. For those who are in the hole, use strong wood for it, and paint inside to make it difficult for moisture to invade. A should be wrapped in thick silk, and the son should be filled with brocade caskets, and each should be safe in his place, so as not to mix with each other, so as not to disturb his nature and taste.
As for the way on the road, it is advisable to be light and stable. Although A is solid, it will be shaken or cracked; the child is delicate, and if it is slightly shaken, it will be afraid of being broken. Those who carry it must choose those who are calm and heavy, so that they know the treasures of the two medicines and take care of them. When the road encounters wind and rain, quickly find a shelter, and do not let the medicine get wet. And during the journey, always check, if you see any abnormality, deal with it quickly.
Also, when you hand over to others, you must clearly state its nature. The strength of the nail and the softness of the child are all related to the effect of the medication. Make the receiver know the details, so as not to misuse it, so as to ensure that this second medicine is used in Tibet and transportation without losing its nature for later use.
