2-(4-fluorophenyl)-7-methyl-4-oxo-4H-chromen-5-yl acetate CAS CATO-C3D-262399

Description

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.

2-(4-fluorophenyl)-7-methyl-4-oxo-4H-chromen-5-yl acetate (CAS CATO-C3D-262399), molecular formula C18H13FO4 and molecular weight 312.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution, 2-(4-fluorophenyl)-7-methyl-4-oxo-4H-chromen-5-yl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2-(4-fluorophenyl)-7-methyl-4-oxo-4H-chromen-5-yl acetate 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.
