View its properties, under normal conditions or as a solid, mostly in powder form, color or due to preparation process and purity, usually white to yellow powder. Its solubility is quite critical. It can show a certain solubility in water, and can form an ionic state to disperse in the aqueous phase. This is because its disodium salt structure easily interacts with water molecules and dissolves through ion-dipole force. However, in organic solvents, such as common ethanol, ether, etc., the solubility is poor, because its structure and the interaction between organic solvent molecules are weak.
When it comes to stability, it can remain relatively stable in a dry environment at room temperature and pressure. However, in case of high temperature, or exceeding a specific temperature limit, the molecular structure may change, triggering a decomposition reaction. Under light conditions, because the molecule contains an azo structure, it is more sensitive to light, and long-term light or azo bonds are broken, which affects its chemical stability. In different acid-base environments, its stability also varies. In acidic media, sulfonic acid groups or protons, which affects the stability of their ionic states; in alkaline environments, if the basicity is too high, or reacts with some functional groups in the molecule, resulting in structural changes.
The melting point, boiling point and other physical parameters of this substance require specific experimental conditions and instruments for accurate determination, and there are differences in different literature reports. However, in general, due to the molecular structure containing multiple polar groups and benzene ring structures, the intermolecular force is strong, and the expected melting point is relatively high. The density of
is also related to the purity and aggregation state of the substance. Although there is a lack of exact literature data, it is speculated that when powdered, the unit volume mass may be slightly higher than that of ordinary organic compounds, because its molecular structure is relatively compact and contains chlorine and other elements with relatively large atomic mass.
