Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of centrally acting agents such as antidepressants and neuromodulators. Its strained cyclopropane ring enhances binding selectivity in bioactive molecules, making it valuable in medicinal chemistry. Also employed in agrochemicals for developing herbicides and plant growth regulators due to its stability and reactivity profile. The hydrochloride salt form improves solubility and handling in aqueous reaction systems.
