The structure of this organic compound is complex, and its physical properties can be inferred from the following aspects:
From the perspective of its structure, it contains multiple hydrocarbon groups such as methyl groups and methoxy groups. The hydrocarbon group is hydrophobic, so the substance is difficult to dissolve in water. At the same time, because it contains many hydrophobic groups, it is speculated that its density is less than that of water, and it can float on the water surface.
The compound contains cyclic structures such as furyl groups and pyridine rings, and has multiple substituents. The intermolecular force is enhanced. Compared with simple hydrocarbons, its melting and boiling point will increase. In addition, due to the tight connection between atoms in the structure, the molecular rigidity is large, and it may be solid at room temperature and pressure.
From the perspective of polarity, although there are polar groups, the overall structure is complex and relatively symmetrical, and the According to the principle of "similar miscibility", the solubility is small in polar solvents, but relatively large in non-polar or weakly polar organic solvents such as benzene and toluene.

This is a complex organic compound whose structure is expressed according to a specific code. It involves a variety of substituents and spatial configurations, just like building a delicate pavilion, and each component has its place and function.

Looking at its structure, (9S, 12E, 14S, 15R, etc.) shows that the spatial orientation of each atom is just like the tenon and mortise structure of a pavilion, which is accurate. Substituents such as 6,18,20-trifluoro group and 14-ethoxy group are like the decoration of a pavilion, which affects its properties.

As for the properties of this compound, because it contains fluorine groups, it may have high chemical stability and fat solubility. Fluorine atoms have high electronegativity, which can change the force between molecules and affect their boiling point and melting point. Alkyl groups such as ethoxy groups may increase their hydrophobicity. Nitrogen-containing heterocycles and epoxy pentacarboxytrienimide groups may give them certain biological activities.

If in the reaction, due to its complex structure, there are many reaction check points. Fluorine groups can participate in reactions such as nucleophilic substitution, nitrogen-containing heterocycles and epoxy structures, or form reactive centers, participate in ring opening, nucleophilic addition and other reactions, just like pavilions can be modified on demand, and each component can play a unique function.

This is a rather complex and domain-specific description of chemical substances. However, it is difficult to find exact and direct applications in many fields involved in "Tiangong Kaiwu". As an ancient scientific and technological masterpiece, "Tiangong Kaiwu" covers various skills such as agriculture and engineering.

The agricultural part of the book details grain cultivation, silkworm breeding, etc. This chemical substance description has little to do with it, because it does not involve the application of such complex organic structures in agriculture. In the textile field, it mainly discusses fiber production and textile processes such as hemp and silk, and there is no trace of this substance.

Handicraft chapters such as pottery, smelting and casting focus on raw material characteristics, temperature control, etc. This complex chemical structure is not directly related to it. Even in the content of salt and sugar production involving chemical processes, it is difficult to find its application.

In summary, according to the skills and knowledge recorded in "Tiangong Kaiwu", this chemical substance is described in its field, and there is no clear corresponding application.

"To obtain this compound, first take a fluorine-containing raw material and combine it with an ethoxy-containing reagent according to a specific ratio. Control temperature and pressure to promote its reaction, and produce a fluorine-containing and ethoxy-containing initial product."

"Second, add a methyl-containing reagent to make the initial product meet, and after catalysis, obtain an intermediate containing heptyl. Then introduce (2-methylpropyl) and triphenyl groups to finely adjust the reaction conditions, such as temperature, time, and amount of agent."

"In addition, the raw materials of naphthalene and related heterocycles are used to obtain parts containing complex heterocyclic structures through several steps such as cyclization and condensation according to a specific reaction path. In the end, this part is merged with the previous intermediate, and through the process of purification, impurities are removed, which is the compound of the target. "

"The whole process of synthesis requires precise control of the reaction conditions of each step, careful selection of reagents and catalysts, in order to obtain high purity and high yield (9S, 12E, 14S, 15R, 16S, 17R, 18R, 19R, 20S, 21S, 22E, 24Z) -6,18,20-trifluoro-14-ethoxy-7,9,15,17,19,21,25-heptomethyl-1 '- (2-methylpropyl) -5,10,26-triphenyl-3,5,9,10-tetrahydronaphthalene [9,4- (epoxypentacarbon [1,11,13] trioxethylene) imidazole [2', 3 ': 7,8] thieno [1,2 - d] pyridine-2,4 '-p].
