Used as an intermediate in organic synthesis, particularly in the preparation of heterocyclic compounds through multicomponent reactions. Its isocyanide group participates in Ugi and Passerini reactions, enabling the formation of complex molecules with potential pharmaceutical activity. The bromo substituent allows further functionalization via cross-coupling reactions such as Suzuki or Heck couplings, making it valuable in medicinal chemistry for building diverse compound libraries. Additionally, the tosyl group acts as a protecting group and stabilizing moiety, facilitating purification and handling during synthesis.
