CAS 1333-39-7
:Phenolsulfonic acid
Description:
Phenolsulfonic acid, with the CAS number 1333-39-7, is an aromatic sulfonic acid characterized by the presence of both a phenolic hydroxyl group and a sulfonic acid group. This compound typically appears as a colorless to light yellow liquid or solid, depending on its form and concentration. It is highly soluble in water, which enhances its utility in various applications. Phenolsulfonic acid is known for its strong acidic properties, making it an effective catalyst in chemical reactions and a useful reagent in organic synthesis. It is commonly employed in the production of dyes, pharmaceuticals, and as a precursor for other chemical compounds. Additionally, due to its phenolic structure, it exhibits antioxidant properties, which can be beneficial in certain formulations. However, it is important to handle this substance with care, as it can be corrosive and may pose health risks upon exposure. Proper safety measures should be observed when working with phenolsulfonic acid in laboratory or industrial settings.
