Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with specific stereochemistry. It plays a crucial role in the production of enantiomerically pure compounds, which are essential for drugs targeting neurological and psychiatric disorders. Additionally, it is employed in organic synthesis to create intermediates for agrochemicals and fine chemicals. Its hydrochloride form ensures stability and solubility, making it suitable for various chemical reactions and formulations.
