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 defined stereochemistry make it valuable for creating enantioselective drugs. Commonly employed in the preparation of antidepressants and attention-deficit/hyperactivity disorder (ADHD) medications due to its ability to influence neurotransmitter activity. Also utilized in asymmetric synthesis to introduce chirality in complex molecules.
