Used in the synthesis of pharmaceutical intermediates, particularly in the development of anti-inflammatory and kinase inhibitor compounds. Its structure supports conjugation in prodrug designs, enhancing bioavailability and targeted delivery. Also employed in research for modifying peptide-like molecules to improve metabolic stability. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to act as a linker with hydrogen bonding and hydrophobic interactions.
