2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2-chlorobenzoate CAS 306730-64-3

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-chlorobenzoate.

2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2-chlorobenzoate (CAS 306730-64-3), molecular formula C23H15ClO5 and molecular weight 406.82 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-chlorobenzoate (C23H15ClO5) 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).

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 manufactures 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 2-chlorobenzoate 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.
