What is the chemical structure of Methyl 3-iodo-l-tyrosinate?
Methyl 3-iodo-L-tyrosinate is an organic compound. This compound is composed of several parts.
The first view of the basic structure of "L-tyrosine", tyrosine is a naturally occurring amino acid. It has a benzene ring structure, which is connected with a hydroxyl group on the benzene ring, and the side chain of the benzene ring is modified by amino and carboxyl groups to form the basic formula of amino acids, showing a unique chemical activity and spatial structure.
Looking at "3-iodine" again, this shows that at the 3rd position of the L-tyrosine phenyl ring, the original hydrogen atom is replaced by an iodine atom. Iodine atoms, due to their large atomic radius and electronegativity differences, significantly affect the electron cloud distribution and steric resistance of molecules, and then change the physical and chemical properties of molecules, such as improving their fat solubility and affecting their reactivity.
The "methyl ester" part, referred to as "Methyl", refers to the ester structure formed after the esterification reaction between the carboxyl group of L-tyrosine and methanol. The introduction of ester groups, on the one hand, changes the polarity of molecules, reduces their solubility in water, and enhances their solubility in organic solvents; on the other hand, ester groups can undergo reactions such as hydrolysis under specific conditions, giving this compound a variety of chemical changes in different environments.
In summary, Methyl 3-iodo-L-tyrosinate is based on L-tyrosine, modified by iodization and methyl esterification, showing unique chemical structures and properties, which may have potential applications in organic synthesis, medicinal chemistry and other fields.

What is the synthesis method of Methyl 3-iodo-l-tyrosinate?
To prepare methyl 3-iodine-L-tyrosine ester, the method is as follows:
Take L-tyrosine as the starting material first, which is the key starting material. Place L-tyrosine in a suitable reaction environment and mix it with the iodine source. The choice of iodine source should be carefully considered, its reactivity, cost and subsequent separation difficulty. Commonly used iodine sources, such as potassium iodide and oxidant synergistic system, or elemental iodine directly participate in the reaction under specific conditions. At the time of the reaction, control the temperature, time and adjust the pH of the reaction system to an appropriate level, so that the specific position (3 position) of the benzene ring of tyrosine can be iodized to obtain 3-iodine-L-tyrosine. This step requires fine operation to increase the purity and yield of the product.
After obtaining 3-iodine-L-tyrosine, it is then met with methanol and suitable esterification reagents. Esterification reagents such as concentrated sulfuric acid, dicyclohexyl carbodiimide (DCC) with 4-dimethylaminopyridine (DMAP), etc. If concentrated sulfuric acid is used, although its catalytic activity is high, it is necessary to pay attention to the selectivity of the reaction and the influence on the substrate, and side reactions may occur in the reaction; if the DCC and DMAP systems are selected, although the cost is high, the reaction conditions are mild and the selectivity is good. At the appropriate temperature and reaction time, the two are esterified to obtain methyl 3-iodine-L-tyrosine ester. After the reaction, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to obtain a high-purity target product.
What are the physical and chemical properties of Methyl 3-iodo-l-tyrosinate?
Methyl-3-iodine-L-tyrosine methyl ester, this material has different properties and has a variety of physicochemical properties.
Looking at its properties, under room temperature, or in a solid state, the color is pure white, like the purity of snow, uniform and fine, or in the shape of crystals, shining, like fine pearls.
When it comes to the melting point, the melting point is about a specific temperature range. This temperature range is the boundary point where it changes from a solid state to a liquid state, just like ice melts in the spring sun and goes through a phase transition. The boiling point is also fixed, and when it reaches this high temperature, it converts from a liquid state to a gaseous state and rises in the air.
In terms of solubility, it shows unique solubility characteristics in organic solvents. For example, in alcohol solvents, like fish getting water, it can be better mutually soluble, just like water and emulsion blend; in ether solvents, it also has a certain degree of solubility, which blends with each other to form a uniform state. However, in water, the solubility is quite small, such as oil floating in water, it is difficult to form a whole. In terms of chemical activity, it contains iodine atoms, and iodine is active, which makes this compound easily replaced in many chemical reactions, such as encountering nucleophiles. Iodine atoms are like active dancers, opening new reaction paths and deriving various products. Its ester group part is also non-idle. It can undergo hydrolysis in an acid-base environment. In case of alkali, ester bonds are broken, just like a delicate device being disassembled to generate corresponding acids and alcohols. And because of the existence of chiral centers in the molecule, it has optical activity. Under polarized light, it exhibits unique optical rotation and can provide different materials for optical research.
What is the price range of Methyl 3-iodo-l-tyrosinate in the market?
The price of methyl-3-iodine-L-tyrosine methyl ester in the market is difficult to determine. The price of this substance often changes for various reasons. First, the preparation method is quite complex, and the materials used also need to be carefully selected. The price of the material can fluctuate if it is expensive and difficult to obtain. If the material relied on is rare and difficult to find, its price must be high; on the contrary, if the material is easy to obtain and cheap, the price may be slightly lower.
Second, the supply and demand of the market is also the key. If many businesses want it, the demand is greater than the supply, the price will rise; if there are few people who want it, the supply will exceed the demand, and the price will fall. Furthermore, the technical skills and regulations of making this thing also have an impact. Advanced technical skills and large-scale production may reduce its cost, but the initial method and small regulation will increase the cost and the price will also be higher.
In addition, different sellers have different prices. Reputable merchants may have stable and slightly higher prices due to their reputation; new merchants are competing for the market, or their prices may be slightly reduced. To sum up, the price of methyl-3-iodine-L-tyrosine methyl ester often fluctuates in a large area, or tens of gold to hundreds of gold per unit, which is difficult to determine a definite number.
