Used in the synthesis of pharmaceuticals and biologically active compounds due to its functional groups that allow for easy modification. The amine and carboxylic acid groups make it suitable for peptide coupling and the formation of amide bonds. Commonly employed in the development of prodrugs and drug delivery systems where controlled release is required. Also utilized in the preparation of surfactants and functional polymers, leveraging its amphiphilic nature. Its structure supports use in biochemical research, particularly in labeling and conjugation techniques.
