Used as an intermediate in the synthesis of sulfa drugs, particularly in the development of sulfonamide-based antibiotics. It serves as a building block in medicinal chemistry for creating compounds with antimicrobial and anti-inflammatory properties. Its tert-butyl group enhances lipophilicity, improving cell membrane penetration in drug design. Also employed in agrochemicals for developing herbicides and plant growth regulators due to its stability and reactivity in sulfonamide coupling reactions.
