Frequently Asked Questions

What are the physical properties of (3E) -3- [ (2-methoxyphenyl) hydrazone] -4-oxo-3,4-dihydronaphthalene-1-sulfonic acid

The physical properties of Wuguan (3E) -3- [ (2-methoxybenzyl) sulfur] -4-oxo-3,4-dihydroquinoline-1-carboxylic acid are as follows:
Its state is usually solid, and it may appear as a white to off-white crystalline powder. This is due to the interaction between molecules, resulting in the formation of an ordered lattice structure. Its melting point is quite critical. After determination, under specific conditions, the melting point is within a certain range, and this characteristic can be used for identification and purification. Due to the different purity of the material, the melting point is also different. The melting point of the pure is fixed and sharp, and the melting point of the impurity is reduced and the melting range is wider.
Its solubility is also an important physical property. In organic solvents, such as common ethanol and acetone, it has a certain solubility. Because the molecular structure contains polar and non-polar parts, it can interact with organic solvents through intermolecular forces. The polar part and the polar solvent attract each other, and the non-polar part interacts with the non-polar solvent, so it can be dissolved. However, in water, the solubility is limited, because the polarity of water molecules is strong, and the intermolecular forces of the substance are difficult to effectively overcome the lattice energy, making it insoluble.
In addition, its density is also an inherent physical property. Although the specific value needs to be accurately measured, the density range can be inferred according to its molecular composition and crystal structure. This property is important in many application scenarios, such as separation, storage, etc. Knowing its density can help to choose the appropriate container and operation method to ensure the proper handling and application of the substance.
