Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes where it contributes to color stability and fastness. It also serves as a precursor in the manufacture of certain pharmaceuticals, enhancing the sulfonamide group in active compounds. Additionally, it finds use in the development of agrochemicals, including herbicides and fungicides, due to its ability to improve molecular specificity and biological activity. Its structural stability makes it suitable in the formulation of heat stabilizers for polymers, especially in polyvinyl chloride (PVC) systems.
