2-[[2-[(E)-2-[8-(Bis(Carboxymethyl)Amino)-6-Fluoroquinolin-2-Yl]Ethenyl]Phenyl]-(Carboxymethyl)Amino]Acetic Acid CAS 137550-81-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 511.46 g/mol gives 2-[[2-[(E)-2-[8-(Bis(Carboxymethyl)Amino)-6-Fluoroquinolin-2-Yl]Ethenyl]Phenyl]-(Carboxymethyl)Amino]Acetic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-[[2-[(E)-2-[8-(Bis(Carboxymethyl)Amino)-6-Fluoroquinolin-2-Yl]Ethenyl]Phenyl]-(Carboxymethyl)Amino]Acetic Acid (CAS 137550-81-3), a certified reference material (molecular formula C25H22FN3O8, MW 511.46 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-[[2-[(E)-2-[8-(Bis(Carboxymethyl)Amino)-6-Fluoroquinolin-2-Yl]Ethenyl]Phenyl]-(Carboxymethyl)Amino]Acetic Acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 511.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
