What are the physical properties of 3-amino-5-chloro-2-hydroxybenzenesulfonic acid
3-Amino-5-bromo-2-fluorobenzoic acid is an organic compound with the following physical properties:
1. ** Properties **: This compound is mostly white to light yellow crystalline powder under normal conditions. Looking at its shape, the powder is delicate and has a certain luster under light. Its solid state is stable, making it easy to store and operate. If many similar organic compounds exist in powder form, it is conducive to full contact and uniform mixing with other reagents in subsequent chemical reactions, thereby improving the reaction efficiency.
2. ** Melting point **: The melting point is in a specific range, about 170-175 ° C. The melting point is the key physical parameter for the identification and characterization of organic compounds. When heated to this temperature range, the lattice structure of 3-amino-5-bromo-2-fluorobenzoic acid is heated, the thermal motion of the molecule intensifies, and the solid state gradually transitions to the liquid state. Accurate melting point can help identify the purity of the compound. If it contains impurities, the melting point may drop and the melting range is widened.
3. ** Solubility **: Slightly soluble in water, although the amino group in the molecule can form hydrogen bonds with water, at the same time, bromine, fluorine atoms and benzene ring have strong hydrophobicity, resulting in poor overall water solubility. However, it is easily soluble in common organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), etc. In dichloromethane, due to the principle of similarity and miscibility, the molecule of the compound and the molecule of dichloromethane are adapted, which can be uniformly dispersed and dissolved to form a clear solution, providing a basis for the selection of reaction medium in organic synthesis.
4. ** Density **: The density is about 1.88 g/cm ³. This value reflects the mass of the substance per unit volume. Density data is crucial when it comes to operations such as quantitative access of the substance, ratio of the reaction system, and separation and purification. The mass of a certain volume of the compound can be accurately calculated by density to ensure the accuracy and repeatability of the experiment.
5. ** Stability **: Under normal temperature and pressure, 3-amino-5-bromo-2-fluorobenzoic acid is relatively stable. However, the amino group has a certain alkalinity and is easy to react with acids; bromine and fluorine atoms are also highly active. Under specific conditions, such as high temperature, strong acid and base or the presence of catalysts, substitution, addition and other reactions may be triggered. Therefore, when storing, it should be placed in a cool and dry place to avoid contact with acid and base and other substances to prevent deterioration.

Is the chemical properties of 3-amino-5-chloro-2-hydroxybenzenesulfonic acid stable?
Looking at your words, I asked whether the chemical properties of 3-amino-5-bromo-2-furanylsalicylic acid are stable. The stability of this compound depends on many factors.
In terms of structure, it contains furan rings, benzene rings and functional groups such as carboxyl groups, amino groups, and bromine. Furan rings have certain aromatic properties, but the existence of oxygen atoms makes the electron cloud distribution of the ring uneven. Under certain conditions, furan rings may react, which affects the overall stability.
Amino groups as power supply groups can increase the electron cloud density of the benzene ring, making it more susceptible to electrophilic attack. Although the bromine atom is a halogen atom and has an electron-absorbing induction effect, it also has a conjugation effect of electrons, which also affects the reactivity of the benzene ring. The carboxyl group is acidic, and in an alkaline environment, it is easy to neutralize and form carboxylic salts, which may change the stability and reactivity of the compound.
Under normal storage conditions, if it is stored in a cool, dry place away from light, and there are no strong oxidants, reducing agents, strong acids, strong bases, etc., this compound may be relatively stable. However, when exposed to high temperature, light, humid environment, or contact with specific chemical reagents, its chemical structure may change, triggering reactions such as hydrolysis, oxidation, and substitution, resulting in reduced stability.
In conclusion, the stability of 3-amino-5-bromo-2-furanoylsalicylic acid is non-absolute and is significantly affected by environmental conditions and contact substances.

What is the production process of 3-Amino-5-chloro-2-hydroxybenzenesulfonic acid?
The production process of 3-amino-5-bromo-2-furanoacrylic acid is as follows:
First take an appropriate amount of furanaldehyde, place it in a reactor, cool it to a specific low temperature in an ice-water bath, and then slowly add a pre-configured solution containing a specific reagent. This process requires strict control of the dropwise addition speed and temperature to ensure a smooth reaction. After the dropwise addition is completed, maintain the low temperature environment and continue to stir for a number of times to make the reaction sufficient. After
, add an appropriate amount of alkaline substances to the reaction system, adjust the pH of the reaction solution to an appropriate range, and then gradually heat up to a certain temperature range to carry out the reaction. Continuous stirring is required during the reaction to ensure that the reactants are fully in contact with the reaction. After the reaction reaches a predetermined time, stop heating and allow the reaction solution to cool naturally.
Next, the cooled reaction solution is treated, and an organic solvent is generally used for extraction to separate the organic phase where the target product is located. During the extraction process, multiple extractions are required to improve the yield of the product. After the extraction is completed, the combined organic phases are dried through a desiccant to remove the moisture contained therein.
Then, the organic solvent in the organic phase is removed by vacuum distillation, and the fraction within a specific temperature range is collected. This fraction is the crude 3-amino-5-bromo-2-furanoacrylic acid.
In order to obtain a high-purity product, the crude product is recrystallized. Select a suitable solvent, dissolve the crude product, heat it to near the boiling point of the solvent, dissolve the product completely, and then cool slowly to allow the product to precipitate in a crystalline form. The crystalline product was collected by suction filtration and washed with a small amount of cold solvent to remove impurities attached to the surface, and finally obtained high-purity 3-amino-5-bromo-2-furanoacrylic acid crystals. The whole production process requires precise control of the reaction conditions of each step to ensure the quality and yield of the product.
