Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of propargylamine-based drugs that exhibit neuroprotective properties. Commonly employed in the preparation of monoamine oxidase inhibitors (MAOIs), which are relevant in the treatment of neurodegenerative disorders such as Parkinson’s and Alzheimer’s diseases. Also utilized in the production of agrochemicals and functionalized polymers due to its reactive alkyne and amine functionalities. Its hydrochloride salt form enhances stability and solubility, making it suitable for use in aqueous reaction systems and biological assays.
