Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for central nervous system (CNS) drugs. It serves as a building block in the preparation of compounds with potential antidepressant and anxiolytic activity. Also employed in the creation of agrochemicals, contributing to the structure of certain herbicides and fungicides. Its cyclopropyl ring enhances metabolic stability in drug design, making it valuable in medicinal chemistry for improving pharmacokinetic properties. Additionally, it finds use in the production of specialty polymers and resins where thermal stability and rigidity are required.
