Chemical Structure

2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 4-tert-butylbenzene-1-sulfonate CAS 301193-66-8 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 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 4-tert-butylbenzene-1-sulfonate.

CATO supplies 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 4-tert-butylbenzene-1-sulfonate (CAS 301193-66-8), a certified reference material (molecular formula C26H24O6S, MW 464.53 g/mol) for analytical method development and quality control.

The molecular framework of 2-(4-Methoxyphenyl)-4-oxo-4H-chromen-3-yl 4-tert-butylbenzene-1-sulfonate (C26H24O6S) is characterized by a steroid core, a sulfone group, 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).

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 4-tert-butylbenzene-1-sulfonate 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.
