Used in pharmaceutical synthesis as a building block for bioactive molecules, particularly in the development of central nervous system agents and enzyme inhibitors. Its strained azetidine ring enhances metabolic stability and influences conformational rigidity, improving selectivity and potency in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its polarity and hydrogen-bonding capacity. Also utilized in the preparation of peptidomimetics and as an intermediate in the synthesis of receptor ligands targeting neurological disorders.
