Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. It serves as a building block in the formation of heterocyclic compounds due to the reactivity of the amide and tosyl groups. Commonly employed in the synthesis of sulfonamide-based drugs, where it helps introduce the benzamide moiety in controlled reactions. Also utilized in research settings for peptide modifications and as a protecting group strategy in multi-step syntheses. Its stability and selective deprotection make it valuable in creating complex molecular structures.
