Chemical Structure

N-Fmoc-L-HomoPhe(3-Cl，4-F)-OH CAS 2350248-70-1 chemical structure

Description

The occurrence of N-Fmoc-L-HomoPhe(3-Cl，4-F)-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Fmoc-L-HomoPhe(3-Cl，4-F)-OH (CAS 2350248-70-1) is a high-purity analytical reference standard with the molecular formula C25H21ClFNO4 and a molecular weight of 453.89 g/mol.

The molecular framework of N-Fmoc-L-HomoPhe(3-Cl，4-F)-OH (C25H21ClFNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), N-Fmoc-L-HomoPhe(3-Cl，4-F)-OH meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
