Used primarily in peptide synthesis, it serves as a key building block for constructing peptides, particularly in solid-phase peptide synthesis (SPPS). The Fmoc group protects the amino group during the synthesis process, while the Trt group safeguards the side chain of lysine, preventing unwanted reactions. This chemical is critical for producing peptides with high purity and specificity, making it valuable in pharmaceutical research, drug development, and the study of protein interactions. Its applications extend to creating peptide-based drugs, vaccines, and biochemical probes for diagnostic purposes.
