Description

CATO manufactures 3-(3-(4-Chlorophenyl)-5-methyl-7-oxo-7H-furo[3,2-g]chromen-6-yl)propanoic acid 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.

3-(3-(4-Chlorophenyl)-5-methyl-7-oxo-7H-furo[3,2-g]chromen-6-yl)propanoic acid (CAS 777857-52-0) is a high-purity analytical reference standard with the molecular formula C21H15ClO5 and a molecular weight of 382.79 g/mol.

The molecular framework of 3-(3-(4-Chlorophenyl)-5-methyl-7-oxo-7H-furo[3,2-g]chromen-6-yl)propanoic acid (C21H15ClO5) 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 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.
