Description :

Overview of Phenolsulfonic Acid

Phenolsulfonic Acid (CAS: 1333-39-7) is a strong aromatic sulfonic acid widely used in industrial chemical synthesis, dyes, pharmaceuticals, and specialty chemical manufacturing. It generally appears as a viscous liquid or crystalline solid and is highly soluble in water due to the presence of the sulfonic acid functional group.

This compound acts as an important intermediate in the production of dyes, detergents, pharmaceutical intermediates, and electroplating chemicals. Because of its strong acidity and reactive aromatic structure, Phenolsulfonic Acid is commonly used in sulfonation reactions, resin manufacturing, and analytical chemistry.

In industrial chemical processes, aromatic sulfonic compounds such as Benzenesulfonic Acid, p-Toluenesulfonic Acid, and Sulfanilic Acid are also widely used for chemical synthesis, dye intermediates, catalysts, and specialty formulations.
