Description

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 supplies 2-((3-(4-Methoxyphenyl)-2-oxo-2H-chromen-7-yl)oxy)acetamide (CAS 869079-70-9), a certified reference material (molecular formula C18H15NO5, MW 325.32 g/mol) for analytical method development and quality control.

Structurally, 2-((3-(4-Methoxyphenyl)-2-oxo-2H-chromen-7-yl)oxy)acetamide (C18H15NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 325.32 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
