    —— Product Detail ——

    Product Overview

    4-Nitro-L-phenylalanine is a nitrated amino acid derivative with the molecular formula C₉H₁₀N₂O₄ and a molecular weight of 210.19 g/mol. This yellow to orange-yellow crystalline powder is a valuable building block for peptide synthesis and drug discovery, featuring a phenylalanine backbone with a nitro group at the 4-position. The nitro group provides unique electronic properties and serves as a versatile handle for further functionalization, including reduction to the amino group. This compound is widely used in the synthesis of peptides and peptidomimetics, as well as in structure-activity relationship studies.

    Synthetic Process

    4-Nitro-L-phenylalanine is synthesized through the following routes:

    • Nitration of L-phenylalanine: L-Phenylalanine is nitrated under controlled conditions to introduce the nitro group at the 4-position.

    • Purification: The crude product is purified by recrystallization or column chromatography.

    Mechanism of Action / Application Principles

    • Peptide Synthesis: Serves as a building block for incorporating 4-nitrophenylalanine residues into peptide sequences.

    • Drug Discovery: The nitro group can be reduced to amine for additional functionalization.

    • Structure-Activity Relationship: Used in SAR studies to optimize peptide properties.
