Fmoc-DAP(ivDDE)-OH is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS). It serves as a key building block for introducing specific functional groups into peptide chains. The ivDDE protecting group is especially valuable for its orthogonality, allowing selective deprotection in the presence of other protecting groups, which is crucial for complex peptide assembly. This compound is often employed in the synthesis of peptides for research applications, including the development of therapeutic peptides, peptide-based drugs, and biochemical probes. Its compatibility with Fmoc chemistry makes it a versatile tool for constructing peptides with high precision and efficiency. Additionally, it is used in the study of protein-protein interactions and the design of peptide mimetics, contributing to advancements in drug discovery and molecular biology.
