Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-Fmoc-L-HomoPhe(4-NO2)-OH.
N-Fmoc-L-HomoPhe(4-NO2)-OH (CAS 205182-66-7) is a high-purity analytical reference standard with the molecular formula C25H22N2O6 and a molecular weight of 446.45 g/mol.
The molecular framework of N-Fmoc-L-HomoPhe(4-NO2)-OH (C25H22N2O6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-Fmoc-L-HomoPhe(4-NO2)-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.
