Chemical Structure
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 3-(5-(3-Chlorophenyl)furan-2-yl)-N-(2,4-dimethoxyphenyl)propanamide (CAS 853312-57-9), a certified reference material (molecular formula C21H20ClNO4, MW 385.84 g/mol) for analytical method development and quality control.
The molecular framework of 3-(5-(3-Chlorophenyl)furan-2-yl)-N-(2,4-dimethoxyphenyl)propanamide (C21H20ClNO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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).
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.
