Description

Sodium 5-Amino-o-Xylene-3-Sulphonate is a key aromatic sulfonate intermediate with significant utility in advanced chemical synthesis. Its value lies in its bifunctional structure, featuring both an amino group and a sulfonate moiety, which makes it a versatile building block for creating more complex molecules. This compound is primarily needed by manufacturers in the dye and pigment, pharmaceutical, and agrochemical industries for the production of specialty chemicals and active ingredients.

Application

• Dye and Pigment Intermediate: A crucial precursor in the synthesis of azo dyes, acid dyes, and reactive dyes, providing color fastness and solubility.
• Pharmaceutical Synthesis: Serves as a building block for active pharmaceutical ingredients (APIs), particularly in compounds requiring sulfonated or aminated aromatic structures.
• Agrochemical Manufacturing: Used in the production of herbicides, fungicides, and other crop protection agents that incorporate sulfonated aniline derivatives.
• Chemical Research & Development: Employed as a standard or starting material in organic synthesis and catalysis research within R&D laboratories.
• Surfactant and Detergent Formulation: Can be utilized to develop specialized anionic surfactants due to its sulfonate functional group.
• Photographic Chemical: Acts as a component in certain photographic developers and other imaging chemicals.
