Looking at its physical properties, at room temperature, it is likely to be in a solid state, or a white to pale yellow powdery substance. Because its molecular structure contains many polar groups, the intermolecular force is enhanced, which is favorable for the formation of solid lattices. In terms of solubility, in view of the fact that there are both hydrophobic groups such as chlorine atoms and trifluoromethyl groups in the molecule, and hydrophilic groups such as amide groups and amino groups, there may be a certain solubility in organic solvents, such as dichloromethane, N, N-dimethylformamide (DMF), etc. The solubility in water may be limited, but due to hydrochloric acid salts, in the presence of an appropriate amount of acid or base, the solubility may change.

Its melting point and boiling point, due to the complex structure and strong molecular forces, the melting point should be high, and a higher temperature is required to break the lattice to cause it to melt; the boiling point is also high, and to make it vaporized, it is necessary to overcome the multiple intermolecular forces.

The stability of this compound is relatively stable under normal conditions due to the presence of fluorine, chlorine and other halogen atoms and amide bonds. In case of high temperature, strong acid or alkali or specific catalysts, it may cause chemical reactions and cause structural changes. Such as in a strong alkali environment, amide bonds or hydrolysis. And because it contains trifluoromethyl, it has a certain degree of chemical inertness and improves the overall stability.
