Description

n-(3-Amino-4-Sulfophenyl)Glycine is a specialized aromatic amino acid derivative featuring both amino and sulfonic acid functional groups. This unique molecular structure makes it a valuable intermediate for synthesizing dyes, pigments, and other functional chemicals. It is primarily sought after by manufacturers in the dyestuff, photographic chemical, and pharmaceutical intermediate industries for its role in creating colorants and bioactive molecules.

Application

• Dye and Pigment Intermediate: A key building block for the synthesis of azo dyes, acid dyes, and reactive dyes used in textiles, leather, and paper.
• Photographic Chemical: Used in the production of color couplers and other agents for photographic films and papers.
• Pharmaceutical Intermediate: Serves as a precursor in the synthesis of certain active pharmaceutical ingredients (APIs) and diagnostic agents.
• Chemical Research & Development: Employed as a reagent in organic synthesis and material science research to develop new functional compounds.
• Specialty Surfactant Synthesis: Can be utilized to create amphoteric or anionic surfactants due to its amino and sulfonate groups.
