Apigenin 7,4-dimethyl ether CAS 5128-44-9

Description

Compared with other compounds in its class, the molecular weight of 298.29 g/mol gives Apigenin 7,4-dimethyl ether distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Apigenin 7,4-dimethyl ether (CAS 5128-44-9), a certified reference material (molecular formula C17H14O5, MW 298.29 g/mol) for analytical method development and quality control.

Based on its molecular formula C17H14O5, Apigenin 7,4-dimethyl ether contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Apigenin 7,4-dimethyl ether 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.
