Description

Sodium 2-Amino-4,4'-Dichlorodiphenylether-2'-Sulfonate is a high-purity, functionalized aromatic sulfonate salt designed for advanced chemical synthesis. This compound serves as a critical intermediate, valued for its unique combination of an amino group, halogen substituents, and a water-sulfonate moiety, enabling precise molecular design. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty dye industries seeking to develop novel active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly for compounds requiring a functionalized diphenyl ether backbone.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators where the dichloro and amino groups impart specific biological activity.
• Dye and Pigment Manufacturing: Acts as a functional intermediate for creating specialized azo dyes and high-stability organic pigments, leveraging its sulfonate group for solubility and the aromatic structure for color.
• Polymer Modification: Employed to introduce ionic or reactive sites into polymer chains for creating specialty resins, ion-exchange materials, or polymers with enhanced properties.
• Research & Development: Serves as a valuable reagent in academic and industrial R&D for exploring new chemical entities and reaction pathways in organic and medicinal chemistry.
