Used in peptide synthesis as a building block for developing bioactive peptides, particularly in research focused on enzyme substrates and inhibitors. Its structure supports studies in protease activity due to the presence of arginine, which is recognized by trypsin-like enzymes. Commonly applied in medicinal chemistry for designing peptide-based drugs and in biochemical assays to investigate cellular processes involving arginine-specific interactions. Also utilized in the preparation of larger peptide sequences for pharmaceutical and diagnostic applications.
