Used as an intermediate in the synthesis of sulfa drugs, particularly in the production of antimicrobial and antifungal agents. It plays a key role in the development of sulfonamide-based pharmaceuticals due to its ability to inhibit bacterial growth by interfering with folic acid synthesis. Also utilized in the preparation of dyes and pigments for industrial applications, where its chemical stability and reactivity contribute to color development and durability. Additionally, it serves as a building block in agrochemicals for creating herbicides and plant growth regulators.
