Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-[(2-oxo-4-phenyl-2h-chromen-7-yl)oxy]acetic acid (CAS 130181-72-5) is a high-purity analytical reference standard with the molecular formula C17H12O5 and a molecular weight of 296.27 g/mol.
The molecular framework of 2-[(2-oxo-4-phenyl-2h-chromen-7-yl)oxy]acetic acid (C17H12O5) is characterized by a flavonoid core, 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).
CATO manufactures 2-[(2-oxo-4-phenyl-2h-chromen-7-yl)oxy]acetic 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.
