Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active ingredients where stereochemistry plays a critical role in biological activity. Its structure supports the formation of complex molecules with high enantioselectivity. Commonly employed in medicinal chemistry for constructing beta-amino acids and other bioactive compounds. Also utilized in asymmetric synthesis due to the stability and reactivity of the carboxylic acid group in enantiomerically pure form.
