Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its rigid cyclopropane structure and amine functionality make it valuable for designing bioactive molecules with high stereoselectivity. Commonly employed in medicinal chemistry for structure-activity relationship studies, especially in serotonin and dopamine receptor modulators. Also utilized in asymmetric synthesis due to its stable chiral center and ability to direct stereoselective transformations.
