Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and biologically active compounds. Its structure allows for incorporation into more complex molecules where the phenylsulfonyl group can act as a protecting group or influence solubility and stability. Commonly employed in the development of central nervous system agents and enzyme inhibitors due to its ability to mimic amine-containing motifs in bioactive molecules. Also utilized in medicinal chemistry research for scaffold modification and structure-activity relationship studies.
