Used in organic synthesis, particularly in multicomponent reactions such as the Ugi and Passerini reactions, to build complex molecules including heterocycles and peptidomimetics. Its isocyanide group reacts with carbonyl compounds, amines, and acids to form amide or lactam structures, making it valuable in medicinal chemistry for drug discovery and library synthesis. Also employed in the preparation of functionalized aromatic compounds for materials science and agrochemical research.
