Used primarily as a building block in organic synthesis, especially in the preparation of pharmaceuticals and agrochemicals. Its reactivity stems from the isocyanate group, which readily reacts with nucleophiles such as amines and alcohols to form ureas and carbamates, respectively. It is valuable in the development of heterocyclic compounds due to the presence of the pyridine ring, which can enhance biological activity. Commonly employed in the synthesis of kinase inhibitors and other bioactive molecules. Also utilized in the preparation of polyurethane-based materials where specific electronic or coordination properties are required. Its ability to coordinate with metals makes it useful in catalysis and in the design of functional materials.
