Chemical Structure

3-((3,4-Dimethylphenyl)sulfonyl)-7-hydroxy-2H-chromen-2-one CAS 866013-26-5 chemical structure

Description

3-((3,4-Dimethylphenyl)sulfonyl)-7-hydroxy-2H-chromen-2-one (CAS 866013-26-5) is a high-purity analytical reference standard with the molecular formula C17H14O5S and a molecular weight of 330.36 g/mol.

3-((3,4-Dimethylphenyl)sulfonyl)-7-hydroxy-2H-chromen-2-one (C17H14O5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 3-((3,4-Dimethylphenyl)sulfonyl)-7-hydroxy-2H-chromen-2-one 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.
