In fine chemical synthesis, it can be used as a key intermediate. For example, in the preparation of some high-end functional dyes, it can give the dye a special color, stability and affinity for different fiber materials by virtue of its unique molecular structure. Taking the synthesis of new fluorescent dyes as an example, the diazo group and naphthalene ring structure of the substance can participate in a series of chemical reactions to construct a complex molecular system with high-efficiency fluorescence properties, so that the dye emits bright and stable fluorescence under specific lighting conditions, and is used in fields such as bioluminescent labeling and anti-counterfeiting printing.
It also plays an important role in the field of materials science. For example, in the process of preparing high-performance photosensitive materials, it can be used as a photosensitive component to take advantage of its light-sensitive properties to generate specific chemical reactions under light, thereby changing the physical or chemical properties of the material to achieve functions such as image recording and lithography. By compounding or copolymerizing with other materials, the surface properties and electrical properties of the material can also be adjusted to broaden the application range of the material.

This substance may be in powder form, due to the intramolecular electron conjugation system, or have a specific color. Since it contains multiple polar groups, such as dioxy, oxo and ammonium sulfonate, it may have a certain solubility in water and can be combined with water molecules by hydrogen bonds. There are many unsaturated bonds and cyclic structures in the
molecule, resulting in its melting point or relatively high. More energy is required to destroy the intermolecular force and lattice structure. Due to the existence of diazo groups and other parts, the stability to light and heat may be poor. When irradiated or heated, diazo groups may undergo reactions such as decomposition, resulting in structural changes of compounds.
Conjugated systems containing naphthalene rings and other large conjugated systems, under the irradiation of specific wavelengths of light, may have fluorescence properties, and electron transitions can produce fluorescence emission phenomena. And because of the presence of ammonium sulfonate group, the aqueous solution may have a certain surface activity, which can reduce the surface tension and produce a directional arrangement at the interface.

Subsequent steps, after multiple rounds of reaction adjustment and structural modification, make the molecule gradually approach the structure of the target product. After each step of the reaction, it is necessary to use analytical methods such as chromatography and spectroscopy to carefully check the purity and structural correctness of the product. If there is any deviation, adjust the subsequent reaction conditions in time.
After the approximate structure is formed, the final refining step is performed. Or by recrystallization, column chromatography and other purification methods to remove impurities and improve the purity of the product, and finally obtain a high purity of 2,5-difluoro-4- {3-methyl-5-oxo-4- [ (E) - {3- [ (2-phenethyl) carbamoyl] phenyl} diazo] -4,5-dihydro-1H-pyrazole-1-yl} benzyl benzoate.
