4-Iodine-1,3-isobenzofurandione, which is an organic compound. It has the following chemical properties:
Its molecule contains the skeleton of isobenzofurandione, and there are iodine atoms connected at the 4 position. From the perspective of reactivity, the iodine atom is an active group, and due to its electronegativity difference and atomic radius factors, various reactions can occur. For example, nucleophilic substitution reactions, iodine atoms can be replaced by other nucleophilic reagents. Due to the high tendency of iodine atoms to leave, it is suitable for nucleophilic reagents to attack and form new chemical bonds.
Furthermore, the structure of isobenzofurandione has certain reactivity. Its carbonyl group can undergo reactions such as nucleophilic addition. The carbon in the carbonyl group has partial positive electricity, which is vulnerable to attack by nucleophiles, and then a series of transformations occur. If it is with alcohols, it may undergo esterification reaction under suitable conditions to generate corresponding ester derivatives.
And because it contains a conjugated system, the compound may have a certain stability. The conjugated system can delocalize electrons and reduce the overall energy of the molecule. This stability affects its reaction behavior in different environments. In some cases of harsh reaction conditions, the conjugated system may protect the molecular structure and avoid overreaction.
In addition, the solubility of the compound is also an important property. According to the principle of similarity and miscibility, it may be slightly soluble in water due to limited molecular polarity. In organic solvents such as dichloromethane and tetrahydrofuran, it may have good solubility, which is of great significance for its separation, purification and choice of reaction solvent.
In summary, 4-iodine-1,3-isobenzofurandione has rich chemical properties, and the interaction of iodine atoms with isobenzofurandione structures endows it with diverse reactivity and physical properties.

The preparation of 4-iodine-1,3-isobenzofurandione is a delicate chemical technique. The method is as follows:
First, the starting material needs to be prepared, usually based on a suitable benzene derivative. Take phthalic anhydride as an example. This is a commonly used starting material because its structure has a similar skeleton to the target product.
Then, the phthalic anhydride is reacted with a specific iodizing reagent. The choice of iodizing reagent is crucial, and the common one is the combination of iodine elemental substance and an appropriate oxidizing agent. The role of this oxidizing agent is to promote the electrophilic substitution reaction between iodine and phthalic anhydride. For example, when a strong oxidant such as nitric acid is combined with iodine, nitric acid can oxidize iodine into a high-valence iodine ion, which has stronger electrophilicity and is easy to attack the aromatic ring of phthalic anhydride.
The reaction system needs to be carried out at a suitable temperature and solvent environment. Suitable solvents can enhance the solubility and contact opportunity of the reactants. For example, halogenated hydrocarbon solvents such as dichloromethane and chloroform are selected. These solvents have good solubility to organic reactants and are relatively stable, without interfering with the reaction process. The regulation of temperature also affects the rate and selectivity of the reaction. Generally speaking, this iodization reaction is mostly carried out at low temperature to room temperature, such as 0 ° C to 25 ° C. Low temperature helps to control the reaction rate and avoid excessive iodization or other side reactions; while appropriate heating can speed up the reaction process and complete the reaction within a reasonable time.
During the reaction process, close monitoring is required. Commonly used monitoring methods such as thin-layer chromatography (TLC). Through TLC, the consumption of reactants and the generation of products can be known in real time to determine whether the reaction is complete.
When the reaction reaches the expected level, the product needs to be separated and purified. This step is usually initially separated by conventional extraction methods, using the difference in solubility between products and impurities in different solvents. Then, the pure 4-iodine-1,3-isobenzofuranedione product was obtained by column chromatography and other fine separation methods, using silica gel as the stationary phase and a suitable eluent.

I think what you are asking is about the price range of "1,3-isobenzofuranedione, 4-iodine -" in the market. However, the price of these substances in the market often changes for many reasons.
First, the purity of this chemical is extremely important. If the purity is high, it is almost flawless, and the price must be high; if it contains impurities, the price should drop. Second, the market supply and demand trend also affects its price. If there are many people who want it, and there are few people who supply it, the price will rise; conversely, if the supply exceeds the demand, the price will fall. Third, the difficulty of preparation also affects its price. If it is difficult to prepare, it requires delicate methods and rare materials, and the price will be high; if it is easy to prepare, the price will be lower.
And the place where it is sold is also related. In prosperous cities, transactions are convenient, logistics is smooth, and the price may be stable; in remote places, transportation is difficult, costs increase, and the price may be high. And different sellers have different prices. Large merchants' goods, or because of brand and quality assurance, have high prices; small merchants' goods, or because of competition, have low prices.
I am sorry, but I do not know the specific price. If you want to know, you can go to the chemical trading office and consult the merchants; or visit the chemical market website to check the listed price; you can also ask the experts in the chemical industry, and they may be able to tell you the approximate price.
