Boc-Val-Val is widely used in peptide synthesis as a protected dipeptide. It serves as a building block for constructing larger peptide chains, ensuring the amino groups remain protected during the reaction process. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it helps maintain the integrity of the peptide sequence. Additionally, it is employed in the development of pharmaceutical compounds, especially in the creation of protease inhibitors and other bioactive peptides. Its stability and ease of deprotection make it a preferred choice in organic and medicinal chemistry research.
