Used as an intermediate in the synthesis of azo dyes and pigments, particularly for producing yellow and orange shades in textile, leather, and paper industries. Its sulfonic acid group enhances water solubility, making it suitable for dyeing processes requiring uniform color distribution. Also employed in the formulation of inkjet inks due to its stability and color fastness. Additionally, it serves as a coupling component in the production of disperse and acid dyes, contributing to improved light and wash resistance in final products.
