Looking at its appearance, it is often powdery, with a light yellow or nearly white color, delicate and uniform. This state is convenient for it to disperse and process in various chemical operations.
When it comes to solubility, this substance can exhibit certain solubility properties in water. Under suitable temperature and stirring conditions, it can partially dissolve in water to form a uniform solution. However, its solubility is not very high, because the molecular structure contains both hydrophilic sulfonic acid groups and hydrophobic naphthalene ring parts, the two check and balance each other, resulting in limited solubility in water.
In terms of melting boiling point, 1-diazo-2-naphthol-4-sulfonic acid has a relatively high melting point. Due to the existence of various forces between molecules, such as hydrogen bonds, van der Waals forces, etc., these forces hold molecules tightly together, requiring higher energy to disintegrate their lattice structure and melt. As for the boiling point, the exact boiling point is difficult to determine because the substance decomposes before reaching the boiling point, or due to poor thermal stability.
Furthermore, the substance is quite sensitive to light and heat. Under light, diazo groups are prone to photochemical reactions, resulting in changes in molecular structure. When heated, it is also easy to decompose, and the decomposition process may be accompanied by color changes. This is because diazo groups, naphthol and sulfonic acid groups are partially heated, and chemical bonds are broken and recombined.
In addition, 1-diazo-2-naphthol-4-sulfonic acid dissolves differently from water in organic solvents such as ethanol and acetone. In polar organic solvents, its solubility may be better than that of water. Due to the polarity and molecular structure of organic solvents, specific interactions can be formed with the compound to help it disperse and dissolve.
