Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of high-performance disperse dyes for polyester and blended fabrics. It contributes to improved lightfastness and color stability in textile applications. Also employed in the formulation of photoactive compounds for use in UV-curable inks and coatings. Its sulfonyl group enhances reactivity in coupling reactions, making it valuable in organic synthesis for pharmaceuticals and agrochemicals.
