Z-Val-NH2 is primarily used in peptide synthesis as a building block for constructing larger peptide molecules. It serves as a protected form of valine, ensuring that the amino group remains intact during the synthesis process. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps in the stepwise assembly of peptides with high precision. Additionally, Z-Val-NH2 is utilized in research and development for studying peptide structures and functions, as well as in the production of custom peptides for pharmaceutical and biochemical applications. Its protective group (Z-group) can be easily removed under specific conditions, allowing for further modifications and elongation of the peptide chain.
