3-methoxypyridine

3-Aminoethoxy vinyl glycine, its main uses are as follows:
This is an important plant growth regulator. In the field of agriculture and horticulture, the effect is significant. First, it can effectively regulate the synthesis of ethylene in plants. Ethylene plays a key role in many stages of plant growth and development, such as fruit ripening, leaf senescence, flower wither, etc. By inhibiting the synthesis of ethylene, 3-aminoethoxy vinyl glycine can significantly delay the ripening process of fruit. When the fruit is stored and transported, the application of this substance can keep the fruit fresh for a long time, reduce the loss of rot, and greatly extend the shelf life. For example, bananas, mangoes and other tropical fruits, after picking, an appropriate amount of 3-amino-ethoxy vinyl glycine can be applied to maintain good appearance and taste during long-distance transportation and long-term storage.
Second, it is also of great benefit to flower preservation. Flowers often wither rapidly due to ethylene induction during sales and viewing. The application of 3-amino-ethoxy vinyl glycine can effectively inhibit the formation of ethylene in flowers, thereby prolonging the ornamental period of flowers, making the flowers bloom longer, and enhancing their commercial value and ornamental value. Whether it is fresh cut flowers displayed in flower shops or flowers planted in garden landscapes, you can use this object to maintain its beautiful posture.
Thirdly, in the field of plant tissue culture, 3-aminoethoxy vinyl glycine also plays an important role. In the process of tissue culture, the production of ethylene sometimes has adverse effects on the growth and differentiation of cultures. Adding an appropriate amount of 3-aminoethoxy vinyl glycine can regulate the level of ethylene in the culture environment, promote the normal growth and differentiation of plant tissues, improve the success rate of tissue culture, and help the reproduction and seedling cultivation of rare plants.

3-Aminoethoxyvinylglycine, its physical properties are as follows:
This substance is mostly white to off-white crystalline powder at room temperature, with fine texture and pure color. Its melting point is critical, about 138-142 ° C. In this temperature range, the substance gradually melts from solid to liquid. This property is crucial for identification and purification.
Solubility is also one of the important physical properties. It is soluble in water and can slowly diffuse and dissolve in water to form a uniform liquid phase system. This property makes it useful in aqueous solution-related reactions or applications. However, its solubility in common organic solvents such as ethanol and ether is poor, and it is mostly in a dispersed and insoluble state in such solvents, and can only form a suspension system.
In addition, the density of 3-aminoethoxy vinylglycine is moderate, although the exact value varies slightly due to measurement conditions, it is roughly within a certain range. Its powder fluidity is acceptable, and it is not easy to affect the quality due to caking and other problems during storage and transportation. Because of its specific physical properties, it has applications in many fields such as chemical industry and pharmaceutical research and development. It can be reasonably processed and used according to these properties to achieve the desired goals.

3-Aminoethoxy vinyl glycine, this physical property is unique. It is a plant growth regulator, and its role is obvious in the process of plant physiology.
Looking at its properties, it is in the shape of white to beige crystalline powder, soluble in water to a certain extent, and has good stability. However, it may change in the case of strong acid and alkali, or high temperature.
On its chemical properties, it has the structure of amine, ethoxy, vinyl and glycine, which gives it specific reactivity. Amino groups are alkali and can form salts with acids; vinyl is active and can react with addition and polymerization. It may be a key step in organic synthesis.
In the regulation of plant growth, 3-aminoethoxy vinyl glycine can inhibit the synthesis of ethylene. Ethylene is a plant hormone, which is related to fruit ripening, leaf senescence, flowering and other things. This substance inhibits ethylene synthesis, which can prolong the ripening of fruits and vegetables, maintain the freshness of fruits and vegetables, and control the opening of flowers and increase the ornamental time.
And in agricultural production, it helps plants resist stress. In case of adversity such as drought and salinity, by inhibiting ethylene synthesis, plants stabilize physiology, enhance their resistance to stress, reduce damage and preserve production. In conclusion, 3-aminoethoxy vinyl glycine is of great use in plant growth regulation and agricultural production due to its unique chemical properties, and is an important agent in agriculture and horticulture.

3-Aminoethoxyvinylglycine, also known as AVG, is commonly synthesized by the following methods:
First, ethanolamine and acrylonitrile are used as starting materials. First, ethanolamine and acrylonitrile undergo an addition reaction. This step needs to be carried out under the action of a suitable temperature and catalyst to generate β-cyanoethyl ethanolamine. Afterwards, β-cyanoethyl ethanolamine is hydrolyzed to convert cyanyl groups into carboxyl groups to obtain β-carboxyethyl ethanolamine. Then β-carboxyethyl ethanolamine is cyclized to form oxazolidinone intermediates. Finally, oxazolidinone intermediates open the ring under specific conditions and introduce aminoethoxy to obtain 3-aminoethoxy vinyl glycine. The raw materials for this route are relatively easy to obtain, but there are many reaction steps, and the reaction conditions of each step need to be precisely controlled, otherwise it is easy to produce more by-products, which affects the yield and purity.
Second, glycine derivatives are used as starting materials. First, the amino and carboxyl groups of glycine are properly protected, and then they react with reagents containing ethoxy vinyl structures to form key carbon-carbon bonds. During the reaction process, suitable bases and solvents need to be selected to promote the smooth progress of the reaction. After the carbon-carbon bond is formed, the protecting group is removed, and then the amino-ethoxy group is introduced through a series of functional group conversion reactions, and the target product is finally obtained. The advantage of this method is that the functional group of glycine can be precisely regulated, which is conducive to improving the purity of the product, but the introduction and removal of the protecting group increases the complexity and cost of the operation.
Third, glyoxylic acid, ethoxy vinyl amine and formaldehyde are used as raw materials. Under specific catalyst and reaction conditions, glyoxylic acid and ethoxy vinyl amine first undergo condensation reaction to form a preliminary skeleton. Then, formaldehyde participates in the reaction, and further functionalization is carried out. Through ingenious design of reaction sequence and conditions, the molecular structure of 3-amino ethoxy vinyl glycine is gradually constructed. This synthesis path is relatively novel, the reaction steps are relatively compact, but the reaction conditions are demanding, and in-depth research is required to optimize the process and enhance the feasibility of industrial production.

3-Aminoethoxyethylene is in the market, and the price range is difficult to determine. The price of this product often changes due to many reasons, such as supply and demand conditions, manufacturing costs, quality differences, and even market conditions.
Looking at the supply and demand, if there are many applicants and few suppliers, the price will increase; on the contrary, if the supply exceeds the demand, the price may decline. Manufacturing costs are also key, and the price of raw materials, energy consumption, labor costs, etc. are all affected by costs. If the cost is high, the merchant will also increase the price in order to protect their profits. Different quality, the price is also different, the price of the high product may be expensive, and the price of the second product may be cheap. And changes in market conditions, such as policy adjustments and competition trends, also make prices fluctuate.
Although it is difficult to determine the range of its price, it can be roughly extrapolated. In the general chemical raw material market, if the quality is average, the price per ton may be between thousands and more than 10,000 yuan. If the quality is excellent and used in high-end fields, such as fine chemicals, pharmaceutical research and development, the price may be higher, tens of thousands per ton, or even higher. However, this is only speculation. To know the exact price, you need to carefully investigate the current market and consult relevant merchants and businesses before you can get a more accurate number.
