5- (2,3-dimethylamino) -1H-indole-2-carboxylic anhydride (1:1) is an organic compound with the following physicochemical properties:
In terms of appearance, this compound is often in a solid state. As for the color, or a white to light yellow powder, this is due to its structure and molecular arrangement. Its melting point is also an important characteristic. Specific intermolecular forces and lattice energy determine its melting point range. Experiments have determined that at about [X] ° C, at this temperature, the lattice structure disintegrates and the substance changes from solid to liquid. In terms of solubility, it exhibits a certain solubility in organic solvents such as dichloromethane and N, N-dimethylformamide. Due to the principle of similar miscibility, the molecules of this compound can form moderate interactions with such organic solvent molecules, such as van der Waals force, hydrogen bond, etc. However, in water, due to the large difference between molecular polarity and water, the solubility is very small. In terms of stability, in conventional temperature and pressure environments, the compound is relatively stable without special chemical reagents or conditions. In case of strong acids, strong bases, or extreme conditions of high temperature and high humidity, the amide bonds and indole rings in its structure may undergo chemical reactions, causing its structure to change. The spectral properties of
cannot be ignored either. In the infrared spectrum, the corresponding characteristic absorption peaks can be observed at specific wavenumbers, such as the C = O stretching vibration peak of the amide bond near [specific wavenumber 1] cm1, and the C-H stretching vibration peak of the indole ring around [specific wavenumber 2] cm1, so that the functional groups in the molecule can be determined. In nuclear magnetic resonance spectroscopy, hydrogen atoms and carbon atoms in different chemical environments will peak at specific chemical shifts to analyze the structure and connection of molecules.

The symbols are strange and the meaning is difficult to understand. However, if you want to know the price range of a certain medicine in the market, you need to explain what kind of medicine it is, where it is sold in the market, and how the time is different.
The change in the price of medicine varies from time to time and place to place, and it is related to the quality, origin, supply and demand of the medicine. If you want to know its exact price, you should ask the local medicine shop, medical clinic, or check the relevant books and market records of medicine. What you said today is too vague, it is difficult to know the price of this medicine. I hope you can tell me the details of the medicine in clear words, so that I can answer your question.
