Used as a key intermediate in the synthesis of various pharmaceuticals, particularly in the production of sulfonamide-based antimicrobial drugs, as well as antivirals and anticancer agents. It also serves in the development of agrochemicals, including herbicides, fungicides, and insecticides, due to its ability to enhance bioactivity. Its heterocyclic structure makes it valuable in creating corrosion inhibitors for metals in industrial applications. Additionally, it is employed in the manufacture of dyes and fluorescent whiteners for textiles and paper. Research explores its potential in coordination chemistry as a ligand for metal complexes with catalytic or biological properties.
