Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and adrenergic compounds. Its chiral amine structure makes it valuable in asymmetric synthesis for producing enantiomerically pure drugs. Commonly employed in the preparation of β-blockers and other bioactive molecules where stereochemistry plays a critical role in activity. Also utilized in research settings for developing novel therapeutic agents and as an intermediate in organic synthesis involving phenethylamine derivatives.
