Description

3-(Potassiosulfo)Benzenecarboxylic Acid is a potassium salt derivative of sulfobenzoic acid, valued for its dual functionality as a sulfonate and a carboxylate. This compound is crucial for applications requiring a water-soluble, anionic intermediate with excellent chelating and dispersing properties. It is primarily sought by manufacturers in the agrochemical, dye, and specialty polymer industries for synthesis and formulation processes.

Application

• Agrochemical Intermediates: Used in the synthesis of modern, water-soluble herbicides and plant growth regulators.
• Dye and Pigment Manufacturing: Acts as a solubilizing and coupling agent in the production of acid dyes and organic pigments.
• Specialty Polymer Synthesis: Serves as a monomer or additive for introducing sulfonate groups into polymers to enhance hydrophilicity and ion-exchange capacity.
• Metal Chelation and Treatment: Employed in water treatment formulations and metal finishing processes as a chelating agent for divalent cations.
• Pharmaceutical Synthesis: Functions as a building block for creating sulfonated active pharmaceutical ingredients (APIs) and prodrugs.
• Detergent and Dispersant Formulations: Utilized as a component in industrial cleaners and scale inhibitors due to its surfactant-like properties.
