Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of compounds with central nervous system activity. It serves as a building block in the preparation of kinase inhibitors and other bioactive molecules due to the presence of primary and secondary amine groups that allow for selective functionalization. Its cyclopentyl and aromatic amine structure enhances lipophilicity and membrane permeability, making it valuable in medicinal chemistry for optimizing drug candidates. Also employed in the creation of specialty polymers and ligands for catalysis where tailored steric and electronic properties are required.
