What are the physical properties of 4-chloro-3- (3-methyl-5-oxo-4, 5-dihydro-1h-pyrazol-1-yl) benzenesulfonic Acid?
4-Chloro-3- (3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-yl) benzenesulfonic acid, which is an organic compound. Looking at its physical properties, it is mostly solid at room temperature and pressure. The cover is solid because of the interaction between atoms in the molecule, resulting in the orderly arrangement of molecules and the formation of a stable lattice structure.
When it comes to appearance, it is often white or white-like powder. This color characteristic is related to the absorption and reflection characteristics of light by its molecular structure. The combination of atoms and chemical bonds in its molecular structure absorbs and reflects light of specific wavelengths in the visible light band, resulting in a white or off-white color.
In terms of solubility, the substance has a certain solubility in water. Due to its molecular structure containing sulfonic acid groups (-SO and H), this group has strong hydrophilicity and can form hydrogen bonds with water molecules, so it can be dispersed and dissolved in water. However, in some organic solvents, such as n-hexane and other non-polar solvents, the solubility is poor. Due to the large difference between the polarity of the molecule and the non-polar solvent, it is difficult to dissolve in such solvents according to the principle of "similar miscibility".
Melting point is also one of its important physical properties. Although the exact melting point fluctuates slightly due to factors such as purity, it is roughly within a specific temperature range. When the temperature rises to the melting point, the thermal motion of the molecules intensifies, which is enough to overcome the lattice energy, and the substance changes from solid to liquid. The existence of this temperature range is related to the magnitude of intermolecular forces and the degree of crystal structure.
In summary, the physical properties of 4-chloro-3- (3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-yl) benzenesulfonic acid, such as state, appearance, solubility, melting point, etc., are determined by its unique molecular structure, and are closely related to its physical properties in chemical, pharmaceutical and other fields.
