Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Methyl-4-oxo-2-phenyl-4H-chromene-3-carboxylic acid (CAS 400083-22-9) is a high-purity analytical reference standard with the molecular formula C17H12O4 and a molecular weight of 280.27 g/mol.
The molecular framework of 6-Methyl-4-oxo-2-phenyl-4H-chromene-3-carboxylic acid (C17H12O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 6-Methyl-4-oxo-2-phenyl-4H-chromene-3-carboxylic 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.
