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 2-((2-(3,4-Dichlorobenzylidene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetic acid (CAS 900894-52-2), a certified reference material (molecular formula C17H10Cl2O5, MW 365.16 g/mol) for analytical method development and quality control.
The molecular framework of 2-((2-(3,4-Dichlorobenzylidene)-3-oxo-2,3-dihydrobenzofuran-6-yl)oxy)acetic acid (C17H10Cl2O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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.
