Benzyl L-leucyl-L-phenylalaninate TFA（Cat No.:I043292）is a synthetic compound used in peptide chemistry. It is an ester derivative where L-leucine and L-phenylalanine are conjugated via an ester linkage, with a benzyl group attached to the phenylalanine residue. The trifluoroacetic acid (TFA) salt form enhances its solubility in organic solvents, which is useful in solid-phase peptide synthesis (SPPS). This compound is employed as a chiral building block or protecting group for peptides, and it may also serve as an intermediate in the synthesis of bioactive peptides, providing stability during peptide formation.
