4-Ethyl-7-methyl-5-((3-oxobutan-2-yl)oxy)-2h-chromen-2-one CAS 307546-52-7

Description

The occurrence of 4-Ethyl-7-methyl-5-((3-oxobutan-2-yl)oxy)-2h-chromen-2-one is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Ethyl-7-methyl-5-((3-oxobutan-2-yl)oxy)-2h-chromen-2-one (CAS 307546-52-7), a certified reference material (molecular formula C16H18O4, MW 274.31 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, 4-Ethyl-7-methyl-5-((3-oxobutan-2-yl)oxy)-2h-chromen-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4-Ethyl-7-methyl-5-((3-oxobutan-2-yl)oxy)-2h-chromen-2-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.
