Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure contains a protected azetidine ring and a hydroxyethoxy side chain, making it valuable for constructing compounds with improved metabolic stability and solubility. Commonly employed in medicinal chemistry for modifying pharmacokinetic properties and enhancing molecular diversity in lead optimization. Also utilized in the preparation of kinase inhibitors and central nervous system agents due to its favorable conformational and polarity characteristics.
