H-Phe-Leu-OH

Drive your peptide synthesis, combinatorial chemistry, and protein engineering studies with H-Phe-Leu-OH (CAS No.: 3303-55-7, CAT No.: SRCP-016). Also known as L-phenylalanyl-L-leucine, this dipeptide is constructed from phenylalanine (an aromatic amino acid) and leucine (an essential branched-chain amino acid), joined via a peptide bond. It serves as a versatile intermediate and building block for constructing larger peptides, peptidomimetics, and exploring structure–activity relationships in bioactive peptide research.

The molecular formula is C₁₅H₂₂N₂O₃ and the molecular weight is 278.35 g/mol. H-Phe-Leu-OH usually appears as a white to off-white crystalline powder, showing excellent solubility in water and DMSO, and stability under standard storage conditions. The robust dipeptide linkage and hydrophobic side chains support biophysical studies, drug design, and development of functional biomolecules.
