What are the physical properties of N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester?
N-acetyl-3,5-diiodo-L-tyrosine Ethyl Ester is one of the organic compounds. Its physical properties are unique and valuable to explore.
Looking at its properties, it is mostly white to white-like crystalline powder under normal conditions, which makes it easy to identify and operate in many chemical scenarios. Its melting point is very critical, about 165-170 ° C. The characteristics of the melting point are like the "ID card" of a substance, providing an important basis for identification and purity determination. At this temperature, the compound changes from solid to liquid state, and this process follows specific physical laws.
Solubility is also an important physical property. The substance is slightly soluble in water, but it exhibits good solubility in organic solvents such as ethanol and chloroform. This difference in solubility is due to the difference between its molecular structure and the interaction between solvent molecules. In organic solvents such as ethanol, its molecules and solvent molecules can form a suitable interaction force to achieve dissolution.
In addition, its stability cannot be ignored. Under normal environmental conditions, if properly stored, it can maintain a relatively stable state. However, care should be taken to avoid direct light and high temperature environments to prevent changes in its structure. Strong light and high temperature may cause the breaking or rearrangement of chemical bonds in molecules, which in turn affect their chemical properties and functions.
In summary, the physical properties of N-acetyl-3,5-diiodo-L-tyrosine Ethyl Ester, from morphology, melting point, solubility to stability, are related to each other, and together build the unique physical properties of the compound, laying the foundation for its application in chemistry, medicine and other fields.
What is the synthesis method of N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester?
To prepare N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester, the method is as follows:
Take l-tyrosine first, use an appropriate acetylating agent, such as acetic anhydride, and under suitable reaction conditions, acetylate the amino group to obtain N-acetyl-l-tyrosine. This step requires temperature control and time control to achieve good yield.
Next, iodize N-acetyl-l-tyrosine with an iodine source, such as iodine elemental and an appropriate oxidant, such as hydrogen peroxide, in a suitable solvent, such as glacial acetic acid. Due to the need to introduce iodine atoms at positions 3 and 5, the precise regulation of reaction conditions is crucial, such as the proportion of reactants, reaction temperature and time, etc., which will affect the position and degree of iodization.
Finally, the obtained N-acetyl-3,5-diiodo-l-tyrosine is esterified with ethanol and condensation reagents, such as dicyclohexyl carbodiimide (DCC), in the presence of a catalyst, to obtain N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester. After the reaction, it is separated and purified by methods such as column chromatography, recrystallization, etc., to obtain high-purity products. After each step of the reaction, appropriate analytical methods, such as thin-layer chromatography and nuclear magnetic resonance, are required to verify the purity and structure of the product and ensure that the synthesis path is correct.
What is the market price of N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester?
I look at the market price of N-acetyl-3,5-diiodo-l-tyrosine Ethyl Ester, which is an important compound in the field of fine chemicals and medicine. However, its market price is like a wave on the river, often changing due to factors such as current situation, supply and demand, origin, and quality.
In the past, this compound may have been expensive due to difficult preparation, complicated processes, and rare raw materials. In the city at that time, if the quality was excellent, the supply was less and the demand was more, the price per gram could reach hundreds of gold.
However, with the passage of time, the technology was new, the preparation method was improved, the raw materials were gradually expanded, and the output was also increased. If the supply exceeds the demand, the price will drop. In today's market, depending on the quality and purity, the price can range from tens of gold to hundreds of gold per gram.
Also, the difference in origin is also related to its price. Produced in other states, or due to customs duties, freight, etc., are more expensive than produced in China. And different merchants have different pricing, probably based on their own costs and profits. Therefore, if you want to know the exact price, you should consult chemical raw material suppliers, pharmaceutical reagent suppliers, and compare their prices in detail.
