Used primarily as an intermediate in the synthesis of sulfonamide antibiotics, this compound plays a key role in pharmaceutical manufacturing. It serves as a building block for antimicrobial agents, particularly in the production of sulfa drugs that inhibit bacterial growth by interfering with folic acid synthesis. Its structure allows for easy modification, making it valuable in developing new bioactive molecules. Additionally, it is employed in research settings for designing novel sulfonamide derivatives with potential therapeutic applications, including anti-inflammatory, antiviral, and anticancer activities.
