N-Fmoc-N-benzyl-L-alanine（Cat No.:I043004）is a derivative of the amino acid L-alanine, featuring a fluorenylmethyloxycarbonyl (Fmoc) protecting group on the nitrogen atom and a benzyl group attached to the side chain nitrogen. This compound is commonly used in peptide synthesis, where the Fmoc group serves as a temporary protecting group for the amino functionality, facilitating the stepwise construction of peptides. The molecular formula is C₂₅H₂₃NO₄, with a molecular weight of 401.46 g/mol. It appears as a white to off-white solid and is soluble in organic solvents like dimethylformamide (DMF) and dichloromethane (DCM). Proper handling and storage in a cool, dry place are essential to maintain its stability and reactivity.​
