Used as a key intermediate in organic synthesis, particularly in the preparation of complex heterocyclic compounds. Its isocyano group participates in multicomponent reactions, such as Ugi or Passerini reactions, enabling the efficient construction of peptide-like structures and nitrogen-containing rings. The tosyl group stabilizes adjacent carbanions and can act as a leaving group, facilitating C–C bond formation. The dimethoxybenzene moiety provides a sterically and electronically tunable aromatic scaffold, useful in developing pharmaceuticals and functional materials. Its reactivity profile makes it valuable in medicinal chemistry for generating diverse compound libraries.
