Used as an intermediate in the synthesis of sulfa drugs, particularly in the production of sulfonamide antibiotics. It plays a key role in pharmaceutical manufacturing where it contributes to the development of antimicrobial agents. Its structure allows for modification into active therapeutic compounds that inhibit bacterial growth by interfering with folic acid synthesis. Also utilized in research settings for developing new bioactive molecules and in the preparation of dyes and optical brighteners due to its aromatic and sulfonamide characteristics.
