Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 466.32 g/mol gives (R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(3-bromophenyl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(3-bromophenyl)propanoic acid (CAS 517905-85-0), a certified reference material (molecular formula C24H20BrNO4, MW 466.32 g/mol) for analytical method development and quality control.
(R)-3-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(3-bromophenyl)propanoic acid (C24H20BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
