Used as a key intermediate in the synthesis of sulfonamide antibiotics, particularly sulfa drugs, which are important in treating bacterial infections. It also serves in the development of agrochemicals, including herbicides and fungicides, due to its ability to enhance the biological activity of active ingredients. Additionally, it finds application in the preparation of dyes and functional materials where nitrogen- and sulfur-containing heterocycles contribute to electronic or optical properties. Its structure supports coordination with metals, making it useful in some catalytic systems and sensors.
