Used in peptide synthesis as a building block, particularly for introducing β-alanine residues into peptide chains. It is commonly employed in solid-phase peptide synthesis (SPPS) due to its Fmoc (fluorenylmethyloxycarbonyl) protecting group, which is easily removable under mild basic conditions. This compound is valuable in creating peptides with specific structural or functional properties, such as enhancing flexibility or altering hydrophobicity. It is also utilized in the development of bioactive peptides, peptidomimetics, and other biomaterials for research and therapeutic applications.
