(2-Aminothiazole-4-yl)acetic acid

(2-Hydroxybutyraldehyde-4-yl) butyric acid, also known as pantothenic acid, is not directly named in Tiangong Kaiwu, but its use can be explored from the perspective of ancient chemical processes.
Pantothenic acid is quite key in the way of pharmaceuticals. Ancient physicians paid attention to the compatibility and delicacy of pharmaceuticals, and pantothenic acid was used as a key raw material to synthesize pantothenic acid, that is, vitamin B. In ancient times, although there was no modern and fine pharmaceutical technology, the need for drug supplementation and treatment was never cut off. Vitamin B plays an important role in human metabolism and nervous system operation. Ancient physicians knew that human health needs to be nourished and nourished. If this nutrient is lacking, it may cause various diseases, such as skin discomfort and digestive disorders. Panolytic acid is the cornerstone of the synthesis of vitamin B. In the pharmaceutical field, it provides help to protect human health.
In addition, it is also effective in the field of food supplementation. The ancient diet, although it does not have a variety of modern additive concepts, attaches great importance to the nutritional gain of food. Panolytic acid can be added to food to increase its nutritional value. The ancient dignitaries pursued exquisite nourishment in the diet. Panolytic acid can be added to the diet to supplement the nutrients needed by the human body and help the body become strong. And although there is no clear understanding of food preservation and preservation today, panolytic acid may have a certain effect on maintaining the quality of food, maintaining the freshness of food and prolonging its edible time.
In addition, it also has potential uses in the production of cosmetics. Ancient women's makeup, heavy on natural things. Pan-solution acid has the ability to moisturize and nourish the skin. If added to ancient facial fat, fragrance powder and other cosmetics, it can moisturize the skin and make it delicate and smooth. Although the production of ancient cosmetics is simple, the requirements for skin care are the same as today. Pan-solution acid can become a good material for cosmetics and add color to women's beauty.

The synthesis methods of (2-aminopyridine-4-yl) acetic acid have existed in ancient times and are diverse. The details are as follows:
First, pyridine is used as the starting material and obtained through multi-step reaction. First, the pyridine is substituted under specific conditions, and an appropriate substituent is introduced, and then the substituent is modified and converted. This process requires careful control of the reaction conditions, such as temperature, pressure, and the proportion of reactants. A slight difference in the pool may cause the reaction to be biased in other ways, or generate by-products, which affect the purity and yield of the product. For example, when introducing an amino group, appropriate reagents and reaction conditions need to be selected to ensure that the amino group is precisely connected to the designated position of the pyridine ring.
Second, it can be converted by other nitrogen-containing heterocyclic compounds. Taking the heterocyclic ring with similar structure as the starting material, and using its structural relationship with (2-aminopyridine-4-yl) acetic acid, the structure of the target molecule is gradually constructed through a reasonable chemical reaction. This approach requires a deep understanding of the reactivity and reaction mechanism of heterocyclic compounds in order to skillfully design the reaction route and achieve efficient synthesis.
Third, the synthesis strategy of transition metal catalysis is adopted. Transition metal catalysts show unique advantages in organic synthesis, which can effectively promote the formation and fracture of various chemical bonds. In this synthesis, specific transition metal catalysts are used to catalyze the coupling reaction and cyclization of the substrate to construct the molecular skeleton of (2-aminopyridine-4-yl) acetic acid. However, the choice of transition metal catalysts is crucial, not only its catalytic activity, but also factors such as cost and toxicity.

What is the price of (2-hydroxybutyraldehyde-4-yl) acetic acid in the market? This is a question about the value of chemical products. To determine its market price, we need to consider many reasons in detail.
Looking at the supply and demand of the market, if the demand for this product exceeds the supply, the price may increase; if the supply exceeds the demand, the price may decrease. The technology of its production is also a major factor. If the yield increases and the cost decreases due to the new technology, the price may change accordingly. And the price of raw materials is also related. If the price of raw materials rises, the price of this product may increase accordingly; if the price of raw materials decreases, the price may also decrease.
Furthermore, the price may vary from region to region and season to season. All kinds of trade policies and tax regulations can affect the price. In prosperous commercial ports, supply and demand are prosperous and frequent trade is frequent, and the price may be different from that in remote areas. When production is booming, the price may be lower than usual; when demand is booming, the price may rise.
However, I searched all over the ancient books, but I couldn't get the exact price of (2-hydroxybutyraldehyde-4-yl) acetic acid. When the chemical industry was not developed in ancient times, such fine chemicals were rare. Today's market price, when you look at the platform and information of chemical trading, and visit all merchants and brokers in the industry, you can get a near-real price. Or ask the chemical industry's professional bank, or check the transaction data, to know the current market price.
