The properties and spatial arrangement of these groups play a key role in its physical, chemical properties and possible biological activities.

This substance is named N, N '-bis (2,3-dihydroxypropyl) -5- [ (5-hydroxy-2- (hydroxymethyl) -1-oxopropyl) amino] -2,4,6-triiodine-N, N' -dimethyl-1,3-benzodiformamide. Its physical properties are as follows:
The appearance of this substance is often white to white crystalline powder. Looking at its properties, the texture is fine, the powder is uniform, and there are no visible impurities. In terms of solubility, it exhibits a certain degree of solubility in polar solvents such as water and ethanol. In water, it can be partially dissolved to form a slightly cloudy but uniformly dispersed system; in ethanol, the degree of solubility is slightly better, and a relatively clear solution can be obtained.
When it comes to the melting point, it has been accurately determined to be within a specific temperature range. This temperature range is the key range for its transition from solid to liquid, reflecting the strength of intermolecular forces. Its stability is quite impressive. Under conventional temperature and humidity environments, it can maintain its own chemical structure intact for a long time and does not easily decompose or deteriorate. In case of extreme conditions such as high temperature, strong acid, and strong alkali, the molecular structure will be damaged and the chemical properties will also change. Its density is calculated to have a specific value, which reflects the mass per unit volume of the substance and has its own unique physical characteristics compared with similar compounds.

View this substance, or make a difference in medicine and pharmaceuticals. Its structure is exquisite, and its groups may interact ingeniously with molecules in organisms. For example, hydrophilic groups such as dihydroxypropyl and hydroxymethyl can enhance the solubility and affinity of the substance in the aqueous environment, and can play a key role in drug delivery, target binding, etc.
Furthermore, the existence of triiodine atoms may endow it with special imaging properties. In the field of medical imaging, iodine is often a key component of contrast agents, which may enable specific parts of the human body to be clearly visible in imaging, helping doctors to understand the secrets in the body and providing clear clues for the diagnosis of diseases.
Or in the field of materials science, its unique structure can participate in the construction of specific materials. By virtue of the interaction between the groups, or can control the physical and chemical properties of the material, such as affecting the stability and flexibility of the material, it is a useful material for the development of new functional materials.

To prepare 1% 2C3-phthalamide, N, N '-bis (2,3-dihydroxypropyl) -5- ((5-hydroxy-2- (hydroxymethyl) -1-oxopropyl) amino) -2,4,6-triiodine-N, N' -dimethyl, the method is as follows:
First prepare all kinds of raw materials, choose high purity of 2,3-dihydroxypropylamine, 5- ((5-hydroxy-2- (hydroxymethyl) -1 -oxopropyl) amino ) - 2,4,6-triiodine-1,3-phthalic acid and other raw materials to ensure the accuracy of the reaction.
In a clean reactor, first pour an appropriate amount of organic solvent, such as dichloromethane or N, N-dimethylformamide, to create a suitable reaction environment. Then slowly add 1,3-phthalic acid derivatives, stir evenly, so that the material is fully dispersed.
With precise temperature control equipment, adjust the temperature in the kettle to a specific range, generally 50 to 80 degrees Celsius. At this temperature, slowly add 2,3-dihydroxypropylamine dropwise, and the dropwise speed needs to be stable, so that the reaction can be fully carried out.
Add it dropwise and continue to stir for several hours to make the reaction system reach equilibrium. During this period, the temperature and stirring rate may need to be fine-tuned according to the reaction process.
When the reaction is coming to an end, use suitable separation methods, such as vacuum distillation, extraction, etc., to remove the organic solvent and unreacted raw materials.
Then, the crude product is refined, and a suitable solvent, such as ethanol-water mixed solvent, can be selected by recrystallization to obtain a high purity of 1% 2C3-benzodiformamide, N, N '-bis (2,3-dihydroxypropyl) -5- ((5-hydroxy-2- (hydroxymethyl) -1-oxopropyl) amino) -2,4,6-triiodine-N, N' -dimethyl product. The whole preparation process requires strict adherence to the operating specifications and control of each link conditions to obtain the ideal product.

This drug is called N, N '-bis (2,3-dihydroxypropyl) -5 - [ (5-hydroxy-2 - (hydroxymethyl) -1 -oxypropyl) amino] -2, 4, 6 -triiodine-N, N' -dimethyl-1,3 -benzodiformamide, the following safety precautions should be paid attention to when using:
First, be sure to check the patient's past medical history before use, especially for those who are allergic to iodine-containing contrast agents. The risk of allergy to this drug is quite high, so it should not be used. People with a history of asthma, allergies, and other allergy-related diseases should also be very vigilant when taking medication. Because the probability of allergies is higher than that of ordinary people, close observation is required during the medication period to prepare strategies for dealing with allergies.
Second, renal function is very important. In people with renal insufficiency, drug excretion is easily blocked, causing accumulation in the body and causing adverse reactions. Before taking medication, renal function needs to be accurately evaluated, and the dose should be adjusted according to the results or other methods should be selected.
Third, this drug is mostly used for injection, and the speed and dose should be strictly controlled during injection. If the speed is too fast or the dose is too large, it is easy to increase the burden on the heart and cause adverse cardiovascular reactions, such as arrhythmia and hypotension. During the injection period, the patient's vital signs should be closely monitored. If there is any abnormality, it should be dealt with immediately.
Fourth, the patient should not be allowed to leave immediately after the medication, and should be observed for a period of time. Some adverse reactions are delayed, so stay for timely detection and treatment. At the same time, inform the patient that if there is any discomfort after the medication, such as rash, itching, breathing difficulties, dizziness, etc., be sure to inform the healthcare workers as soon as possible.
Fifth, special groups of people need to be extra cautious in the use of drugs. Pregnant women use drugs, and drugs affect the fetus through the placenta, which is not necessary; breastfeeding women use drugs, or affect the baby with milk secretion, need to weigh the pros and cons; the elderly and children, whose physical functions are different from ordinary people
