Primarily used in biochemical and pharmaceutical research as a starting material or intermediate in the synthesis of peptides and proteins. Commonly employed in studies on enzyme mechanisms involved in cleaving or modifying peptide structures, particularly enzymes specific to modified tyrosine structures, such as acetylation. Also utilized in targeted drug delivery systems to enhance cell membrane permeability. Its structure improves water solubility and stability under biological conditions, making it suitable for developing molecules requiring high absorption and in vivo stability. As a specialty chemical, it serves as a niche additive in advanced formulations.
