3% 2C5-dibromosalicylic acid, an organic compound. Its physical properties are as follows:
Looking at its morphology, under room temperature and pressure, it often takes the shape of white to light yellow crystalline powder, which is easy to identify and distinguish. Its color is pure, without variegation, highlighting its high purity.
Smell the smell, usually slight, does not have a strong pungent or special odor, which is conducive to creating a more comfortable environment in practical application and operation.
When it comes to melting point, it is generally between 195 and 198 ° C. Melting point is one of the important physical properties of a substance. This temperature range is relatively clear and stable, providing an important basis for its identification and purification. When the temperature reaches this range, the substance converts from solid to liquid, and the phase state changes.
In terms of solubility, it is slightly soluble in water, but soluble in organic solvents such as ethanol, ether, and chloroform. This difference in solubility makes it possible to choose suitable solvents for dissolution, separation, or reaction operations according to their characteristics in different chemical experiments or industrial production scenarios. Low solubility in water indicates that the interaction force between it and water molecules is weak; while relatively high solubility in organic solvents reflects the existence of more compatible interactions with organic solvent molecules, such as van der Waals force, hydrogen bond, etc.
These physical properties are of great significance in many fields such as chemical industry and medicine. In the design of chemical synthesis paths, its melting point, solubility and other properties need to be considered to determine suitable reaction conditions and separation and purification methods; in pharmaceutical research and development applications, its morphology, odor and solubility are related to the dosage form design, stability and bioavailability of drugs.

3,5-Dinitrosalicylic acid is chemically stable. This substance contains nitro and carboxyl groups, which have strong electron-absorbing properties, and carboxyl groups can ionize hydrogen ions.
Under normal circumstances, 3,5-Dinitrosalicylic acid can exist stably at room temperature and pressure, and can be stored for a long time in a dry environment without significant deterioration. However, it is more sensitive to heat. When heated to a certain extent, the molecular structure will change, or cause decomposition reactions. When the temperature is too high, the nitro group may detach, causing its structure to change, and may even be dangerous due to violent reactions.
In the field of chemical synthesis, 3,5-dinitrosalicylic acid is often used as an intermediate in organic synthesis. Based on its stable chemical properties, when participating in many reactions, it can be converted according to a predetermined path and provide reliable reaction results. However, because of its nitro group, it has certain oxidation properties. When encountering a reducing agent, the nitro group may be reduced, showing an unstable side.
In an acid-base environment, the carboxyl group of 3,5-dinitrosalicylic acid can react with a base to form a salt, and the resulting salt may be stable or different from the original substance. However, under general weak acidic, neutral and weakly basic conditions, without other strong reagents, its chemical properties can remain stable. Only in strongly acidic or strongly alkaline and high temperature environments, the molecular structure may change greatly.
In summary, 3,5-dinitrosalicylic acid is chemically stable under conventional conditions, but its stability can be challenged when affected by specific environmental factors. When using and storing this substance, appropriate measures should be taken according to its characteristics to ensure its stability and safety in use.

There are various paths for the synthesis of 3,5-dibromosalicylic acid. The following are described in detail.
First, salicylic acid is used as the starting material and obtained by bromination reaction. Place the salicylic acid in an appropriate reaction vessel, add an appropriate amount of solvent, such as glacial acetic acid, etc. Then, under low temperature and stirring, slowly add bromine. Bromine reacts with the phenolic hydroxyl ortho-position in salicylic acid to generate 3,5-dibromosalicylic acid. This process requires careful control of the reaction temperature to prevent side reactions from occurring. If the temperature is too high, bromine may overreact, causing other positions on the benzene ring to be brominated and forming impurities. And the speed of dropwise addition also needs to be appropriate. If it is too fast, the reaction will be violent, and it is not easy to control the temperature; if it is too slow, it will take too long.
Second, salicylic acid can be protected first. For example, the phenolic hydroxyl group is protected with an appropriate protective group, and then brominated. Common protective groups include acetyl groups, etc., which can be acetylated by the reaction of acetic anhydride with salicylic acid. After protection, salicylic acid reacts with brominating reagents, such as N-bromosuccinimide (NBS), under specific conditions. NBS is a milder brominating reagent, which can better control the bromination position. In a suitable catalyst and solvent environment, bromine atoms can be selectively introduced at the 3,5 positions of the benzene ring. After the reaction is completed, the protective group is removed, and the alkali solution such as sodium hydroxide is treated to hydrolyze the acetyl group to regain the phenolic hydroxyl group to obtain 3,5-dibromosalicylic acid. Although this method is slightly complicated, it can effectively improve the purity and selectivity of the product.
Third, other compounds containing benzene rings can also be tried as starting materials to construct target molecules through multi-step reactions. For example, resorcinol is used as the starting material, an appropriate substituent is introduced first, and the position and type of the substituent are adjusted through a series of reactions. Finally, 3,5-dibromosalicylic acid is obtained through bromination and carboxylation. This path requires fine design of each step of the reaction, which requires strict reaction conditions. However, if the design is exquisite, it may open up new synthesis ideas and avoid the shortcomings of some traditional methods.

The price of 3,5-dichlorosalicylic acid in the market often varies with quality and quantity and market conditions, so it is difficult to be sure.
Looking at the market conditions in the past, its price fluctuates. Or because of the abundance of production, the price rises and falls. If the origin is smooth and the output is abundant, the price may stabilize and drop slightly; in case of natural disasters, the production loss will decrease, and the price will rise. Or because of the number of buyers, the price will be high if you want to be prosperous, and the price will be low if you want to be weak.
And this medicine is useful in fields such as engineering and medicine. Industrial dyeing, incense, and medicine are used as antibacterial and anti-inflammatory agents, and they have a wide range of uses, so their price is also influenced by the demand of various domains.
Roughly speaking, in ordinary times, the price per kilogram is about 100 yuan, but in case of sudden changes in supply and demand, there may be big differences. As low as seventy or eighty yuan, as high as one hundred and twenty or thirty yuan, or even more expensive. The market situation is changeable, and its price is difficult to be limited to a certain amount. Buyers can get a suitable price when they observe the real-time market conditions.
