Description

9-Fluorenone-2,7-Disulfonic Acid Dipotassium Salt is a high-purity, water-soluble derivative of fluorenone, characterized by its disulfonic acid groups in the 2 and 7 positions, neutralized as the dipotassium salt. This compound serves as a versatile and critical intermediate and building block in advanced organic synthesis, particularly valued for introducing sulfonated, hydrophilic moieties into larger molecular frameworks. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to develop active ingredients, dyes, and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of sulfonated drug candidates, potentially enhancing solubility and bioavailability.
• Agrochemical Synthesis: Used in creating novel herbicides, fungicides, or plant growth regulators that require a polar, sulfonated component.
• Dye and Pigment Manufacturing: Acts as a precursor for water-soluble fluorescent dyes, pigments, and optical brighteners.
• Polymer Chemistry: Monomer or modifier for producing sulfonated polymers with specific ion-exchange, hydrophilic, or conductive properties.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organic reactions and material science applications.
• Electrolyte Additive: Potential use in specialized battery or electroplating formulations due to its ionic character.
