To prepare methyl 3-iodine-4-pyridinecarboxylate, the method is as follows:
First take 4-pyridinecarboxylic acid, dissolve it in an appropriate amount of organic solvent, such as dichloromethane, cool it to about 0 ° C, slowly add an appropriate amount of methanol and catalytic concentrated sulfuric acid, and heat it for a number of refluxes. This step is to esterify 4-pyridinecarboxylic acid and methanol to form methyl 4-pyridinecarboxylate. After the reaction is completed, the reaction solution is cooled, neutralized to neutral in saturated sodium bicarbonate solution, then extracted with dichloromethane, dried with anhydrous sodium sulfate, and the solvent is removed by rotary evaporation to obtain 4-methyl pyridinate crude product. Purified by column chromatography to obtain pure 4-methyl pyridinate.
Then, dissolve the resulting 4-methyl pyridinate in a suitable solvent, such as N, N-dimethylformamide, add an appropriate amount of iodine substitution reagent, such as N-iodosuccinimide (NIS), and add an appropriate amount of initiator, such as azodiisobutyronitrile (AIBN), under nitrogen protection, heat to an appropriate temperature, and react for several hours. This is an iodine substitution reaction, which allows methyl 4-pyridinecarboxylate to introduce iodine atoms at the 3rd position. After the reaction is completed, the reaction liquid is cooled, poured into ice water, extracted with ethyl acetate, dried with anhydrous sodium sulfate, and the solvent is removed by rotary evaporation to obtain a crude product. Then purified by column chromatography, the target product 3-iodine-4-pyridinecarboxylate is obtained.
This synthesis method involves multiple steps. The reaction conditions of each step need to be precisely controlled to obtain a purer product, and safety needs to be paid attention to during the process, and various reagents and instruments should be used correctly.

Today there are 3-iodine-4-pyridinecarboxylate methyl ester, its market price is difficult to determine. In the market, the price of these chemicals often varies for a variety of reasons. If the source of the material is wide and narrow, the difficulty of preparation, and the situation of supply and demand can all affect its price.
If in the past, if this chemical was obtained from rare raw materials, the preparation method was complicated and abnormal, many fine steps and harsh conditions were required, and the preparation was rare, and the number of people who needed it would be high. Or it can reach thousands of gold, which is easily purchased by extraordinary people.
However, if times change and the raw materials become more and more abundant, the preparation method is also simple due to the advancement of science and technology, the number of preparations is increasing, the market supply is sufficient, and the demand has not increased greatly, the price may be greatly reduced, and it is unknown to the hundred gold or so.
And the market situation varies from place to place. In Kyoto, Dayi, where commerce and trade converge, the competition is fierce, and the price may be slightly flat; and in remote places, the circulation is inconvenient, and the price may increase again. Therefore, in order to know the exact market price, it is necessary to carefully investigate the market of chemical materials in various places and consult various merchants before you can get it.

Methyl 3-Iodine-4-pyridinecarboxylate is one of the organic compounds. When storing and transporting, many things must be paid attention to to to ensure its quality and safety.
First, store this compound in a cool, dry and well-ventilated place. Because of the cool environment, it can avoid chemical changes such as decomposition caused by excessive temperature. Dry conditions are also indispensable, because moisture can easily cause reactions such as hydrolysis, which will damage its purity. With good ventilation, volatile gases that may accumulate can be dispersed in time to avoid potential safety hazards. And it should be kept away from fire and heat sources to prevent the risk of fire or explosion. Due to its flammability, it is easy to react violently in case of open flames and hot topics.
Furthermore, when storing, it should be stored separately from oxidizing agents, reducing agents, acids, alkalis and other substances. If different types of chemicals come into contact with each other, or cause uncontrollable chemical reactions, resulting in dangerous accidents. The packaging of this compound should also be well sealed to avoid deterioration in contact with air.
As for transportation, caution is also required. Transportation vehicles must be equipped with corresponding varieties and quantities of fire fighting equipment and leakage emergency treatment equipment. In this way, if an accident occurs on the way, it can be dealt with in time. During transportation, ensure that the container does not leak, collapse, fall, or damage. When loading and unloading, it should be handled lightly to avoid package damage caused by brutal operation and material leakage. And when transporting, it should be driven according to the specified route, and do not stop in densely populated areas and residential areas, in case of leakage, endangering the safety of many people.
In this way, when storing and transporting 3-iodine-4-pyridinecarboxylate methyl ester, follow the above guidelines to achieve safe and proper purposes.
