In terms of solubility, in view of its structure containing ester groups, amino groups, nitro groups and other groups, in organic solvents, such as common ethanol, acetone, etc., or have a certain solubility. Because the ester group itself has a certain lipophilicity, in polar organic solvents, it will partially dissolve by means of intermolecular forces; while the amino group has a certain alkalinity, or interacts with some acidic organic solvents to enhance solubility. However, in water, because the overall structure is not highly hydrophilic, the solubility may be limited.

In terms of melting point, its specific molecular structure determines the type and strength of intermolecular forces, and then has a specific melting point. There are hydrogen bonds, van der Waals forces, etc., in the molecule, and these forces interact to maintain the stability of the solid-state lattice. When the temperature rises to the melting point, the molecule obtains enough energy to overcome these forces, the lattice disintegrates, and the substance changes from solid to liquid.

The boiling point is also determined by the intermolecular forces and the relative molecular mass. The compound has a relatively large molecular mass and complex intermolecular forces, resulting in a high boiling point. To make the substance boil, energy needs to be provided to overcome the attractive forces between molecules and turn the molecules from the liquid phase to the gas phase.

The density is affected by the degree of close arrangement of molecules and the relative molecular weight. Due to the many types of atoms in the molecular structure, the complex spatial structure, the molecular arrangement or tight, and the relative molecular weight is large, the density or larger.

The refractive index is related to the molecular polarizability. The compound structure contains a conjugated system (thiophene ring, benzene ring, etc.), and the electron cloud can be polarized, so that the refractive index may have a specific value, which can affect the direction and speed of light propagation in it.

3 + - + thiophenecarboxylic acid, 2 - [[ (2,6 -difluorophenyl) methyl] (propoxycarbonyl) amino] -4 - [ (dimethylamino) methyl] -5 - (4 -nitrophenyl) -, ethyl ester This material, when storing and transporting, many matters need to be paid attention to.

Its chemical properties are active, and it is very easy to change when exposed to light and heat. Under light, chemical bonds are easily broken, resulting in structural mutation, damage to efficacy or function. Therefore, when storing, it must be placed in a light-shielding container, such as a brown glass bottle, to prevent light from invading. And it needs to be stored in a cool place, the temperature should be controlled between 15 and 25 degrees Celsius, away from heat sources, because high temperature can promote its reaction rate to speed up and reduce stability.

Furthermore, it is quite sensitive to humidity. Moisture can lead to hydrolysis and damage the molecular structure. Therefore, the humidity of the storage environment must be strictly controlled, and the relative humidity should be 40% to 60%. When transporting, the packaging must be tight to prevent moisture from penetrating. It can be wrapped in moisture-proof materials, such as desiccant, placed inside the package to maintain a dry environment.

In addition, this compound is toxic, and personnel protection is essential during operation and transportation. Operators must wear protective clothing, protective gloves and goggles to avoid skin contact and eye splashing. In case of inadvertent contact, rinse with plenty of water quickly and seek medical attention in time. During transportation, follow relevant regulations on the transportation of hazardous chemicals and choose suitable transportation tools to ensure transportation safety and prevent environmental pollution and personal injury caused by leakage.
