In summary, 3-cyanotyrosine has important application potential in many fields such as medicine, materials, biochemistry and agriculture. With the continuous deepening of research, its application prospects will be broader.

3 - The synthesis of nitrate and water (nitric acid) has been known since ancient times. Although the method is not detailed in Tiangong Kaiwu, it can be explored in ancient books.
In the past, the ancients used green alum (ferrous sulfate) to place in a retort kettle, sealed and heated. The green alum is decomposed by heat, and the text says: "Five catties of green alum, put it in a crock pot, seal it, and calcine it with civil and military fire. The gas is smoked, and it is made with medicine. Calcined and taken out." The decomposition of green alum can obtain iron oxide, sulfur dioxide and sulfur trioxide, and sulfur trioxide can contact water to form sulfuric acid. This sulfuric acid is then co-heated with saltpeter (potassium nitrate), and the saltpeter is decomposed by heat to release the nitrate in potassium nitrate, which can be combined with hydrogen ions in sulfuric acid to obtain nitric acid. The principle of its chemical reaction, although the ancients did not express it in today's chemical symbols, they achieved this skill by practice.
There is another method, which uses realgar (As S) to be co-refined with saltpeter and turpentine. Realgar contains sulfur, reacts with saltpeter, and turpentine supports combustion, which prompts the reaction to occur. After this refining, a mixture containing nitric acid can also be obtained. Although it is not pure, it is also an attempt of the ancients to synthesize nitric acid. This is the wisdom of the ancients. At the beginning of chemical synthesis, they explored the method of synthesizing nitrate with experience and practice, laying the foundation for the development of later chemistry.

3-Boranamine ethers have specific physical and chemical properties. The color of boranamine ethers is often a colorless to light yellow transparent liquid, which is clear in appearance and resembles jade liquid. Its taste, or a weak special smell, is not pungent and intolerable.
As for its melting point and boiling point, the melting point is quite low. At room temperature, it is difficult to form a solid state, and it is mostly a flowing liquid. The boiling point varies depending on its specific structure and purity, but it is within a certain temperature range, depending on the force between molecules. Its density is slightly lighter than that of water. If placed in water, it can float on the surface of the water, just like a boat floating on blue waves.
In terms of solubility, boranamine ethers are mostly well miscible in organic solvents, such as ethers, hydrocarbons, etc., and are like water emulsion. This is due to the adaptation between the molecular structure and the molecular forces of organic solvents. In water, its solubility is limited, only slightly soluble, which is due to the difference between the polarity of its molecules and the polarity of water.
Its chemical properties are also interesting. In boranamine ethers, the presence of boron and nitrogen atoms gives them unique reactivity. Boron atoms have the characteristics of electron deficiency and are easy to accept electron pairs, while nitrogen atoms have lone pairs of electrons and can provide electrons. Therefore, they can participate in a variety of organic reactions, such as nucleophilic substitution and addition reactions. And under appropriate conditions, it can be used as a reducing agent to demonstrate its unique chemical efficacy, just like a weapon in the hands of skilled craftsmen, performing a different kind of brilliance on the stage of chemical reactions.

3 - The price range of blue amino acid calcium in the market is about three taels to five taels per catty of silver. This price is not constant and varies with the supply and demand of the market and the production situation.
If the weather is smooth, the production area is wide, and the production is abundant, the price will tend to go down. There are many lids but those who seek them are limited. If businesses want to sell them quickly, they must reduce their prices to attract customers. If a certain spring, the weather is good, and the raw material production is prosperous, the 3 - of the blue amino acid calcium entering the market is abundant, and the price will drop to three taels of silver per catty.
On the contrary, if there is a famine, the raw material will be damaged and the production will be reduced, and the demand will be high. For example, if a certain place suffers from a flood in summer, the raw materials are lost, and the production plummets. However, the doctors and households need it all, so the business then raises the price, which can reach five taels of silver per catty.
And the quality of the craftsmanship and the quality of the quality are also related to the price. Those who are refined and of high quality must have a higher price than regular products. There are workshops with new techniques, which are pure and effective, and their price is often one or two taels higher per catty than that of ordinary people.
In addition, the distance to the place of sale and the difficulty of transportation also have an impact on the price. In remote places, the difficulty and cost of transportation are high, and the price is higher than that of Dayi, the capital. If it is difficult to transport a long way beyond the Great Wall, the price is one or two more silver per cat
