Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-((4-Fluorophenyl)sulfonyl)-8-methoxy-2H-chromen-2-one.
CATO supplies 3-((4-Fluorophenyl)sulfonyl)-8-methoxy-2H-chromen-2-one (CAS 1351840-89-5), a certified reference material (molecular formula C16H11FO5S, MW 334.32 g/mol) for analytical method development and quality control.
The molecular framework of 3-((4-Fluorophenyl)sulfonyl)-8-methoxy-2H-chromen-2-one (C16H11FO5S) is characterized by a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
