3-(4-Chlorophenoxy)-6-ethyl-7-hydroxy-2-methyl-4h-chromen-4-one CAS 885458-55-9

Description

The occurrence of 3-(4-Chlorophenoxy)-6-ethyl-7-hydroxy-2-methyl-4h-chromen-4-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(4-Chlorophenoxy)-6-ethyl-7-hydroxy-2-methyl-4h-chromen-4-one (CAS 885458-55-9), a certified reference material (molecular formula C18H15ClO4, MW 330.76 g/mol) for analytical method development and quality control.

3-(4-Chlorophenoxy)-6-ethyl-7-hydroxy-2-methyl-4h-chromen-4-one (C18H15ClO4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

As a certified reference material (CRM), 3-(4-Chlorophenoxy)-6-ethyl-7-hydroxy-2-methyl-4h-chromen-4-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
