Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure features a protected azetidine ring, which is valuable in medicinal chemistry for enhancing metabolic stability and influencing molecular conformation. The hydroxyethyl side chain allows for further functionalization, enabling conjugation or attachment to other pharmacophores. Commonly employed in the preparation of enzyme inhibitors and receptor modulators, especially in research targeting central nervous system disorders and metabolic diseases.
