Chemical Structure
Description
CATO supplies Ethyl 2-{[2-(4-methoxyphenyl)-4-oxo-4H-chromen-3-yl]oxy}acetate (CAS 100064-06-0), a certified reference material (molecular formula C20H18O6, MW 354.35 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 2-{[2-(4-methoxyphenyl)-4-oxo-4H-chromen-3-yl]oxy}acetate (C20H18O6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 2-{[2-(4-methoxyphenyl)-4-oxo-4H-chromen-3-yl]oxy}acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
