Z-Tyr-NH2 is commonly used in peptide synthesis as a building block for creating more complex peptide structures. It is particularly useful in the development of peptide-based drugs and research compounds due to its ability to mimic natural amino acids. This chemical is also employed in biochemical studies to investigate enzyme-substrate interactions and protein folding mechanisms. Additionally, Z-Tyr-NH2 is utilized in the production of peptide libraries for high-throughput screening in drug discovery. Its protective group (Z-group) ensures stability during synthetic processes, making it a reliable choice for peptide chemists.
