Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihistamines and other bioactive molecules. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building nitrogen-containing heterocyclic compounds. It is also employed in the preparation of ionic liquids and as a ligand in catalytic systems, where it helps stabilize metal complexes in organic transformations. Additionally, it finds use in materials science for designing functional polymers and sensors due to its ability to coordinate with metals and participate in hydrogen bonding.
