Chemical Structure
Description
As a certified reference material (CRM), (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(5-bromo-2-chlorophenyl)propanoic acid 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.
(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(5-bromo-2-chlorophenyl)propanoic acid (CAS 2002401-84-3) is a high-purity analytical reference standard with the molecular formula C24H19BrClNO4 and a molecular weight of 500.77 g/mol.
The molecular framework of (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(5-bromo-2-chlorophenyl)propanoic acid (C24H19BrClNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
