2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2,4-dichlorobenzenesulfonate CAS 301193-70-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2,4-dichlorobenzenesulfonate.

2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2,4-dichlorobenzenesulfonate (CAS 301193-70-4), molecular formula C22H14Cl2O6S and molecular weight 477.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2,4-dichlorobenzenesulfonate (C22H14Cl2O6S) is characterized by a flavonoid core, a sulfone group, 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2,4-dichlorobenzenesulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
