This compound is widely used in peptide synthesis as a protected form of lysine. It serves as a key building block in the production of peptides, ensuring the lysine side chain remains protected during the synthesis process. The Boc group safeguards the amino group, while the Tfa group protects the epsilon-amino group of lysine, preventing unwanted reactions. This allows for selective deprotection and precise control over peptide chain assembly. It is particularly valuable in solid-phase peptide synthesis (SPPS) and the development of complex peptide structures for research, pharmaceuticals, and biotechnology applications. Its stability and compatibility with various coupling reagents make it a reliable choice for synthesizing peptides with high purity and efficiency.
