Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and fine chemicals. Its structure allows for selective alkylation reactions, making it valuable in the development of active pharmaceutical ingredients (APIs). Commonly employed in the formation of β-amino alcohols and other nitrogen-containing compounds due to its reactivity with nucleophiles. Also utilized in the synthesis of chiral auxiliaries and protecting groups in peptide chemistry. Its stability and reactivity profile make it suitable for controlled reactions under mild conditions.
