Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-blockers and other cardiovascular drugs. It serves as a chiral building block in organic synthesis, enabling the construction of complex molecules with high stereoselectivity. Commonly employed in the preparation of alpha-hydroxy esters and beta-amino alcohols through nucleophilic substitution or reduction reactions. Also utilized in the development of agrochemicals and fine chemicals where controlled stereochemistry is required. Its reactivity allows for easy modification in multi-step synthetic pathways, making it valuable in research and industrial settings.
