Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in organic synthesis, enabling the introduction of sulfonyl functional groups into complex molecules. Its halogen substituents allow for further modification via cross-coupling reactions, making it valuable in medicinal chemistry for creating diverse compound libraries. Also utilized in the preparation of agrochemicals and bioactive molecules where structural specificity is required.
