Chemical Structure
Description
CATO supplies (9H-Fluoren-9-yl)MethOxy]Carbonyl L-2-Amino-4-bromo-4-pentenoic acid (CAS 220497-60-9), a certified reference material (molecular formula C20H18BrNO4, MW 416.27 g/mol) for analytical method development and quality control.
The molecular framework of (9H-Fluoren-9-yl)MethOxy]Carbonyl L-2-Amino-4-bromo-4-pentenoic acid (C20H18BrNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures (9H-Fluoren-9-yl)MethOxy]Carbonyl L-2-Amino-4-bromo-4-pentenoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
