This compound usually appears in a solid state due to the strong interaction between molecules, which makes the molecules closely arranged to form a stable aggregate state. In terms of color, it often has a specific color, or due to the presence of chromophores in the molecular structure, the electron transition absorbs visible light of a specific wavelength.

In terms of solubility, because the molecule contains multiple sulfonic acid groups, it has a certain hydrophilicity. It may exhibit good solubility in water and can form a uniform dispersion system. However, in non-polar organic solvents, the solubility may be poor due to the weak force between the molecules and the non-polar solvent.

Melting point is also an important physical property. When heated to a specific temperature, the thermal motion of the molecule intensifies, overcoming the intermolecular force, causing the solid lattice to disintegrate and transform into a liquid state. The melting point depends on the molecular structure and interaction, and the exact value needs to be determined experimentally.

The density reflects the mass of the substance per unit volume, and is related to the degree of molecular compactness and relative molecular weight. The density of the compound is affected by the way of molecular stacking and the weight of the constituent atoms, or is accurately determined by experimental means.

In addition, this compound is crucial to the stability of light and heat. Some chemical bonds or functional groups in the molecule may change under the action of light and heat, which affects their properties and applications. Under light, the chromophore structure may change, causing color changes; at high temperature, chemical bonds may break, triggering decomposition reactions. Therefore, exploring its light and thermal stability is of great significance to determine its storage and use conditions.
