Used primarily as an intermediate in the synthesis of sulfonamide antibiotics, this compound plays a key role in pharmaceutical manufacturing. Its structure allows for the development of antimicrobial agents that inhibit bacterial growth by interfering with folic acid synthesis. It is also utilized in the production of dyes and pigments due to its aromatic and sulfonamide functional groups, contributing to color stability and solubility. Additionally, it serves in research settings for developing new bioactive molecules and enzyme inhibitors.
