5 Amino 2 4 6 Triiodo 1 3 Benzenedicarboxylic Acid

5-Amino-2,4,6-tribromo-1,3-phthalic acid is an organic compound. It has the following chemical properties:
1. ** Acidic **: This compound contains a carboxyl group (-COOH), and the hydrogen atoms in the carboxyl group can be partially ionized, so it is acidic. In water, it can dissociate hydrogen ions (H ^) and neutralize with bases. For example, when reacted with sodium hydroxide (NaOH), the carboxyl group will combine with hydroxide ions (OH ^) to form water and the corresponding carboxylate. The chemical equation of the reaction can be expressed as follows: 5-amino-2,4,6-tribromo-1,3-phthalic acid + 2NaOH → 5-amino-2,4,6-tribromo-1,3-sodium-phthalate + 2H 2O O. This acidic property makes it play a role in the reaction and regulation of some acid-base systems.
2. ** Substitution reaction **: Because of its substituent groups such as amino (-NH -2) and bromine atom (Br) attached to the benzene ring. Amino is the power supply radical, which can increase the electron cloud density of the benzene ring and make the benzene ring more prone to electrophilic substitution. For example, under appropriate conditions, it can react with acyl chloride. The nitrogen atoms in the amino group will attack the carbonyl carbon of the acyl chloride, and the chlorine atoms will leave to form amide compounds. This reaction can be used in organic synthesis to construct more complex nitrogen-containing organic molecular structures.
3. ** Reaction of bromine atoms **: The bromine atoms on the benzene ring are highly active. Under certain conditions, such as in the presence of strong nucleophiles, bromine atoms can be replaced by nucleophiles. If reacted with sodium alcohol (RONa), bromine atoms can be replaced by alkoxy groups (-OR) to form benzene derivatives containing alkoxy groups. This property provides the possibility for this compound to participate in various organic reactions, realize structural modification and functionalization.
4. ** Redox reaction **: Amino groups can be oxidized under certain conditions, such as when exposed to strong oxidizing agents, amino groups may be oxidized to nitro (-NO ²), or other oxidation state changes may occur. At the same time, if the compound is in a suitable redox system, its overall structure may undergo corresponding electron transfer and chemical bond changes, and then participate in many redox-related chemical processes and reaction mechanisms.

The synthesis of 5-amino-2,4,6-tribromo-1,3-phthalic acid is a key issue in the field of organic synthesis. Although "Tiangong Kaiwu" does not directly discuss the synthesis of this specific compound, it contains a lot of traditional chemical process wisdom, or it can be used for reference to deduce the synthesis path of this compound.
To synthesize 5-amino-2,4,6-tribromo-1,3-phthalic acid, phthalic acid can be used as the starting material. The structure of phthalic acid contains two carboxyl groups, which can undergo a specific substitution reaction. Prospective bromination reaction can make phthalic acid react with bromine under suitable conditions. Bromine has high activity, and bromine atoms can be selectively introduced at specific positions in the benzene ring in the presence of suitable catalysts such as iron powder or iron tribromide. After precise control of reaction conditions, such as reaction temperature, ratio of reactants and reaction time, bromine atoms can be mainly substituted at positions 2, 4, and 6 to obtain 2,4,6-tribromophthalic acid.
Next, amino groups need to be introduced. This step can be achieved by nitro substitution and then reduction. First, 2,4,6-tribromophthalic acid is reacted with a mixed acid of concentrated nitric acid and concentrated sulfuric acid, and nitro groups are introduced into the benzene ring. The introduction of nitro groups requires strict control of the reaction conditions to prevent excessive nitrification. After obtaining 2,4,6-tribromo-5-nitrophthalic acid, the nitro group is reduced. Common reduction methods include iron powder and hydrochloric acid as reducing agents, or catalytic hydrogenation. In the presence of suitable catalysts such as palladium carbon, hydrogen is introduced, and the nitro group can be reduced to an amino group, resulting in 5-amino-2,4,6-tribromo-1,3-phthalic acid.
The synthesis process needs to pay attention to the precise control of the reaction conditions at each step, and the separation and purification of intermediate products are also crucial to ensure the purity and yield of the final product. Although this exact synthesis is not contained in "Tiangong Kaiji", its concept of material conversion and process control is also instructive for the construction of this synthesis idea.

When storing 5-amino-2,4,6-tribromo-1,3-phthalic acid, there are several issues that need to be taken into account.
First, this substance should be stored in a cool, dry and well-ventilated place. If it covers its properties or is disturbed by temperature and humidity, if it is placed in a warm and humid place, it may cause changes in its properties, and even affect its quality and effectiveness. For example, during the hot summer, if there is no appropriate temperature control and dehumidification equipment in the storage place, moisture immersion may cause the compound to deliquescent, thereby damaging its chemical structure and losing its original properties.
Second, when it is separated from oxidizing agents, acids, bases and other chemicals. This is because 5-amino-2,4,6-tribromo-1,3-phthalic acid has a specific chemical activity. When it encounters the above-mentioned substances, it may cause violent chemical reactions, such as oxidation, neutralization, etc., which can cause material loss in light, and trigger the risk of explosion in heavy. Endangering storage safety. In the past, there was a careless storage, and chemicals with compatible properties were stored adjacent to each other, which could not be ignored.
Third, the storage place should be equipped with suitable devices to contain leaks. If a leak occurs, it can be stored and disposed of in time to prevent it from spreading and polluting the surrounding environment. And the leakage may be toxic to a certain extent, which is harmful to the human body and the environment. Therefore, it is necessary to follow the relevant procedures and clean it properly to ensure the safety of personnel and the cleanliness of the environment.
Fourth, a special person should be set up to inspect the storage situation regularly. Check whether the packaging is intact. If there is any damage and the material escapes, deal with it quickly. And record the environmental parameters such as temperature and humidity. If there is any abnormality, adjust it immediately to ensure that the storage conditions of 5-amino-2,4,6-tribromo-1,3-phthalic acid are constant and stable, and maintain its quality.

5-Amino-2,4,6-tribromo-1,3-phthalic acid, this is a rather rare organic compound that is occasionally used in scientific research, medicine and other fields. However, its market price range is difficult to determine, because it is made by multiple factors.
The first to bear the brunt is the preparation cost. Synthesizing this compound involves complicated processes, high raw materials, and specific reaction conditions and equipment. All of these lead to high preparation costs and ultimately affect the selling price.
Furthermore, market supply and demand are also key. If at some point, there is a surge in demand for scientific research projects or pharmaceutical R & D, and the supply is limited, the price will rise; conversely, if the demand is weak and the supply is abundant, the price will decline.
In addition, manufacturers and sales regions also have an impact. Different manufacturers have different technologies and cost controls, and their pricing is different; the economic level and market competition in the sales region also affect their prices.
Although it is difficult to determine the exact price range, it is common sense that the price may remain high due to the difficulty of preparation and the particularity of the application field. In the fine chemical raw material market, the price per gram of such special organic compounds may range from tens of yuan to hundreds of yuan, or even higher, depending on the quality, purity and actual market conditions.
