1 Iodo 4 Methylsulfanyl Benzene

1 - iodo - 4 - (methylsulfanyl) benzene, the Chinese name is often 4 - methylthioiodobenzene. The main use of this substance is.
First, in the field of synthesis, it is very important. It can be made from a variety of reactions, such as even antibodies, for the development of more complex molecules. For example, in the cross-coupling reaction of catalysis, its iodine atom activity is excellent, and it can generate reactions such as alkenyl groups and aryl boric acids, forming carbon-carbon compounds, and synthesizing aromatic compounds with specific properties. This compound is very important in the fields of materials science, physics and chemistry.
Second, in the process of chemical research, due to its specific properties, it may be used as a basic element of molecular properties. The existence of methylthio-functional iodine atoms can change the physical properties of molecules, such as fat solubility, molecular properties, etc., which can affect the interaction of molecular targets and provide possible starting materials for the research of new kinds of compounds.
Third, in terms of material science, it may be used to synthesize materials with special properties. From the chemical modification, other functional properties can be introduced to improve the properties of materials such as optical properties, photoluminescence, etc., and used in the development of materials such as optical diodes (OLEDs) and semi-optical materials.

1 - iodo - 4 - (methylsulfanyl) benzene, the Chinese name is often 4 - methylthioiodobenzene. This material has the same physical properties, and I will show it one by one.
Its outer color is often solid, and the color is often light to brown, just like the color of ancient books, with a slightly deep feeling. As for the melting, it is between 48 and 52 ° C, just like the limit of the melting of ice and snow at the turn of winter and spring. When encountering this degree, the solidification is not liquid.

and boiling, usually at 150-152 ° C, the temperature rises so high that it is just like the heat of Dan, and the material is rising from the liquid. Its density is 1.73 g/cm ³, which is heavier than water, just like gold stone sinking in the bottom of the water.
In terms of solubility, 4-methylthioiodobenzene is soluble in water, and water is the source of life. However, when it is soluble in water, such as ethanol, ether, and chloroform, it is soluble, just like when it comes together, and can be dispersed and homogenized in the solution.
Its low evaporation rate means that under normal conditions, the stability is not very low, and it is not easy to show its body in the air. This material is rational for its survival and use, and also needs to be considered to prevent its properties from being degraded due to environmental factors. Therefore, the physical properties of 1-iodo-4- (methylsulfanyl) benzene are the cornerstone of its properties, which affect its use in the chemical field.

1 - iodo - 4 - (methylsulfanyl) benzene, the Chinese name is often 4 - methylthioiodobenzene. Its chemical properties are determined by phase.
In this compound, the iodine atom is directly attached to the benzene, and the iodine atom has a certain activity. In the presence of an iodine nucleus and the antigens are suitable, the iodine atom can be placed. For example, in some antigens, the iodine atom is replaced by an antigens such as an antigens group and an amino group, and the antigens are replaced by antigens.
The methylthio group (-SCH) on the benzene has solitary antigens on its sulfur atom, which can cause some antigens, such as the formation of some gold antigens. However, due to the co-effect of benzene, the activity of methylsulfanyl is reduced. In addition, benzene itself is aromatic, and the addition of benzene is generally reversed, and it is more of a substitution inverse. However, due to the existence of iodine atoms and methylsulfanyl groups, it affects the cloud density distribution on benzene, which changes the activity and positional properties of the benzene substitution inverse.
In terms of normal and special effects, 1-iodo-4- (methylsulfanyl) benzene can maintain a certain qualitative. However, under specific chemical reactions, the iodine atom and methylsulfanyl group parts in the molecule can be transformed into phases and exhibit their chemical activities.

1-Iodo-4- (methylsulfanyl) benzene, that is, 1-iodo-4- (methylthio) benzene, the synthesis method is as follows:
First, p-methylthioaniline is used as the starting material. First, p-methylthioaniline is reacted with sodium nitrite in a hydrochloric acid solution. This process requires low temperature operation to prevent the decomposition of diazonium salts, such as controlling the temperature at 0-5 ° C. After the diazotization reaction is completed, p-methylthiobenzene diazonate is formed. Next, the diazonium salt is mixed with potassium iodide solution, and the reaction is heated. The diazonium group is replaced by an iodine atom to obtain 1-iodine-4- (methylthio) benzene. Although this method step is more cumbersome, the raw material is relatively easy to obtain.
Second, 4-methylthiobenzoic acid is used as the starting material. First, 4-methylthiobenzoic acid is esterified with alcohols such as methanol under the catalysis of concentrated sulfuric acid to generate methyl 4-methylthiobenzoate. After that, the benzene ring of methyl benzoate is iodized by a halogenating agent, such as the combination of iodine element and red phosphorus. This reaction requires suitable reaction conditions. For example, at a certain temperature and reaction time, iodine atoms can replace hydrogen atoms on the benzene ring to form methyl 1-iodine-4- (methylthio) benzoate. Finally, the target product 1-iodine-4- (methylthio) benzene can be obtained by hydrolysis and re-acidification under alkaline conditions. This method involves multi-step reactions such as esterification, halogenation and hydrolysis, which requires high operation, but can effectively achieve the synthesis of the target substance.
Third, p-bromoiodobenzene and sodium methyl mercaptan are used as raw materials. In a suitable organic solvent, such as N, N-dimethylformamide (DMF), p-bromoiodobenzene and sodium methyl mercaptan undergo nucleophilic substitution reaction. The sulfur anion in sodium methyl mercaptan attacks the carbon atom connected to the bromine atom in p-bromoiodobenzene, and the bromine ion leaves to generate 1-iodine-4- (methylthio) benzene. The reaction steps of this method are relatively simple, the conditions are mild, and the yield is relatively considerable.

1-Iodo-4- (methylsulfanyl) benzene, that is, 1-iodo-4-methylthiobenzene, should pay attention to many key points when storing and transporting this substance.
The first to bear the brunt is the temperature and humidity of the storage environment. This substance should be stored in a cool, dry place, and must not be exposed to high temperature or humidity. High temperature may cause chemical reactions to occur, accelerating deterioration; humid environment may cause reactions such as hydrolysis, which may damage its quality.
Furthermore, it is necessary to pay attention to its isolation from other substances. 1-Iodine-4-methylthiobenzene should be avoided from co-storage and transportation with oxidants, strong acids, strong alkalis, etc. Due to its active chemical properties, it is easy to be oxidized in case of oxidants, and uncontrollable reactions may occur in case of strong acids and alkalis, which may even lead to dangerous conditions, such as explosion, generation of harmful gases, etc.
Packaging is also a key link. Packaging must be tight to ensure that there is no risk of leakage. Usually, corrosion-resistant packaging materials, such as specific plastic containers or glass containers, should be used, and appropriate sealing measures should be taken to prevent air, moisture, etc. from invading and affecting its quality.
During transportation, special care should also be taken. The means of transportation must be kept clean and free of other chemical residues. And to avoid violent vibration and collision, due to excessive vibration collision or packaging damage, and then cause leakage. At the same time, transport personnel should be familiar with the characteristics of this substance and emergency treatment methods. In case of emergencies, they can respond quickly and properly to ensure the safety of personnel and the environment from pollution.
