This state is usually solid. Due to its specific molecular structure, intermolecular forces cause it to exist in this state at room temperature and pressure.

In terms of melting point, this compound has a specific melting point value. The melting point is affected by factors such as intermolecular interactions, molecular symmetry and rigidity. The chemical bonds and group interactions within the molecule make it necessary to reach a specific temperature before the molecule can obtain enough energy to overcome the lattice energy, so as to convert from solid to liquid.

In terms of solubility, it may exhibit certain solubility in organic solvents such as chloroform and dichloromethane. This is because the molecular structure of the compound contains hydrophobic alkyl chains, such as 2-ethylhexyl, which interact with the non-polar part of the organic solvent and follow the principle of similar miscibility. However, in water, due to the limited polarity of the molecule as a whole and the presence of many hydrophobic groups, the solubility is poor.

In addition, the compound may have certain thermal stability. Chemical bonds within molecules, such as carbon-carbon bonds, carbon-sulfur bonds, etc., have a certain bond energy and can maintain the stability of molecular structures within a certain temperature range. However, when the temperature is too high and the bond energy is not enough to resist external energy input, the molecular structure may be damaged, triggering reactions such as decomposition.

Its appearance may vary depending on purity and crystallization. When pure, it may be white to slightly yellow powder or crystalline, which is related to the arrangement of molecules and the scattering and absorption characteristics of light.
