Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. Its strained cyclopropane ring combined with the reactive ethynyl and amine groups allows for selective transformations in organic synthesis. It is especially valuable in the preparation of neuroactive drugs, including those targeting epilepsy and anxiety disorders, due to its ability to mimic or modulate neurotransmitter structures. The hydrochloride salt form enhances stability and solubility, making it suitable for use in multi-step reactions under controlled conditions.
