L-Phenylalanine, 4-[(1,1-dimethylethoxy)carbonyl]-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-

4-[(1,1-Dimethylethoxy)carbonyl]-N-[(9H-fluoren-9-ylmethoxy)carbonyl]-L-phenylalanine is a versatile compound used in chemical synthesis as a protective group for amino acids. By selectively masking the amino and carboxyl groups of the L-phenylalanine molecule, this compound enables chemists to manipulate specific functional groups during multi-step organic synthesis. This protection strategy is crucial in peptide synthesis, where precise control over reaction pathways and functional group reactivity is essential to achieve high yields and purity of the final peptide product.
