(S)-2-Amino-3-(4-hydroxyphenyl)-N-(4-methyl-2-oxo-2H-chromen-7-yl)propanamide 2,2,2-trifluoroacetate CAS 201860-68-6 chemical structure

Description

The occurrence of (S)-2-Amino-3-(4-hydroxyphenyl)-N-(4-methyl-2-oxo-2H-chromen-7-yl)propanamide 2,2,2-trifluoroacetate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-2-Amino-3-(4-hydroxyphenyl)-N-(4-methyl-2-oxo-2H-chromen-7-yl)propanamide 2,2,2-trifluoroacetate (CAS 201860-68-6), a certified reference material (molecular formula C19H18N2O4C2HF3O2, MW 452.38 g/mol) for analytical method development and quality control.

The molecular framework of (S)-2-Amino-3-(4-hydroxyphenyl)-N-(4-methyl-2-oxo-2H-chromen-7-yl)propanamide 2,2,2-trifluoroacetate (C19H18N2O4C2HF3O2) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
