1 3 Benzenedicarboxamide N N Bis 2 3 Dihydroxypropyl 5 Hydroxyacetyl Amino 2 4 6 Triiodo

The analysis of the chemical structure of this compound is as follows:
This is an iodine-containing amide compound, and its basic structure is derived from 1,3-phthalamide. On the benzene ring, a substitution reaction occurs at a specific position. At position 5, a (hydroxyacetyl) amino group is connected, which gives the molecule a specific chemical activity and reaction check point, or can participate in many subsequent chemical reactions.
At the same time, positions 2, 4, and 6 are occupied by iodine atoms. The introduction of iodine atoms greatly changes the physical and chemical properties of the molecule, such as increasing its density and affecting the polarity of the molecule. Furthermore, the N, N 'position is connected to two 2,3-dihydroxypropyl groups. This dihydroxypropyl structure, because it contains multiple hydroxyl groups, can enhance the hydrophilicity of the molecule, and can also participate in the formation of hydrogen bonds, affecting the interaction between molecules.

By substituting iodine atom, (hydroxyacetyl) amino group and dihydroxypropyl group at specific positions, a unique chemical structure is constructed, giving it different chemical and physical properties.

1% 2C3-Phthalamide, N, N '-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodide, this substance is called iodoxanol, and its main use is in medical medicine.
Iodoxanol is a non-ionic, dimer, hexaiodine, water-soluble X-ray contrast agent. It is widely used in the field of medical imaging today. In terms of angiography, such as cerebral angiography, coronary angiography, peripheral arteriography, etc., by injecting iodoxanol, the shape, course, stenosis, obstruction and other lesions of blood vessels can be clearly displayed, helping doctors accurately diagnose vascular diseases. In enhanced CT scanning, it can improve the contrast between the diseased tissue and normal tissue, make the lesion more prominent, and help doctors detect and distinguish minor lesions and judge the scope and nature of the lesion. It is of great significance for the diagnosis and staging of various diseases such as tumors. In urography, it can display the shape of the renal pelvis, calyx, ureter and bladder, helping to diagnose congenital malformations, stones, tumors and other diseases of the urinary system.
Due to its relatively low permeability, low viscosity and good tolerance, this drug plays a key role in many angiographic examinations, providing an important basis for doctors to accurately diagnose the disease, and occupies an indispensable position in the process of modern medical diagnosis.

1% 2C3-benzodiformamide, N, N '-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodine compound, this substance has the following physical properties:

At the same time, the substance may exhibit absorption peaks under specific wavelengths of light, and its absorption characteristics can be precisely determined by spectral analysis techniques, thus further understanding its molecular structure and composition.

To prepare 1% 2C3-phthalamide, $N $, $n '$-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodide, the method is as follows:
Prepare an appropriate amount of raw materials, take 1,3-phthalic anhydride and 2,3-dihydroxypropylamine, and place them in a clean reactor in an appropriate proportion. The environment in the kettle needs to be carefully controlled, and the temperature should be slowly raised to a specific range, about [X] ° C, and under an inert gas atmosphere, such as nitrogen protection, to avoid adverse reactions between the raw materials and the outside world. In this step of the reaction, it is necessary to continue stirring to make the two fully blend. When the reaction has gone through [X], the preliminary product can be obtained.
Then, the preliminary product is mixed with the pre-prepared (hydroxyacetyl) amino-2,4,6-triiodine compound. When mixing, the purity of the reaction system should also be ensured. After that, an appropriate amount of catalyst is added, which needs to meet the characteristics of the reaction and can speed up the reaction process. When the temperature is adjusted to [X] ° C and the reaction is maintained [X], the stirring period is not stopped to make the reaction comprehensive and sufficient.
After the reaction is completed, the product is extracted and separated with a suitable solvent to remove impurities. Then, the product is concentrated by vacuum distillation. After the recrystallization process, a suitable solvent is selected, such as ethanol-water mixed solvent, so that the purity of the product can be improved, and finally 1% 2C3-phthalamide, $N $, $n '$-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodide can be obtained. Each step requires fine operation, and strict control of temperature, ratio, time and other factors to obtain satisfactory products.

1% 2C3-benzodiformamide, N, N '-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodine There are many things to pay attention to during use. The characteristics of this agent are unique, so use it with caution.
The first safety protection, it has certain chemical activity, or it may irritate the skin, eyes and respiratory organs. Therefore, when using, it is necessary to adapt protective equipment, such as gloves, goggles and masks, to avoid direct contact with the body.
Furthermore, the environment of use also needs to be paid attention to. When operated in a well-ventilated place, to prevent the accumulation of volatile gas from the drug and damage to human health. If used in a confined space, ventilation equipment must be turned on to keep the air flowing smoothly.
The preparation and dosage are also critical. Read the instructions carefully before use, and prepare according to the prescribed method and dosage. Do not change it. If the dosage is too much, it may cause adverse reactions; if it is too little, it will be difficult to achieve the desired effect.
After use, properly dispose of the remaining drugs and waste. Do not dump at will, and store and handle them in accordance with relevant regulations to avoid polluting the environment.
In addition, the sensitivity of your mileage may vary. Try it on a small scale before use to see if there are any allergies and other uncomfortable reactions. If you feel unwell in the middle, such as itchy skin, redness and swelling, poor breathing, etc., stop the operation immediately and seek medical treatment.
All uses of this 1% 2C3-benzodiformamide, N, N '-bis (2,3-dihydroxypropyl) -5- [ (hydroxyacetyl) amino] -2,4,6-triiodine should observe the above things to ensure safe and effective use.
