Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its aromatic and aliphatic structural features, enabling the formation of complex molecules with biological activity. Also employed in the preparation of agrochemicals and specialty polymers where cyclic amine functionality is required. Its cyclopentyl group enhances lipophilicity, making it valuable in optimizing drug absorption and metabolic stability.
