Used as a key chiral intermediate in the synthesis of beta-blocker pharmaceuticals, particularly in the production of (S)-propranolol and other cardioselective agents. Its stereochemistry enables high enantioselectivity in drug synthesis, improving therapeutic efficacy and reducing side effects. Also employed in asymmetric synthesis for developing adrenergic receptor modulators. Commonly utilized in research settings for catalyzing enantioselective transformations and in the preparation of optically active amines.
