Chemical Structure

3-Methylflavone-8-carboxylic Acid CAS 3468-01-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 280.27 g/mol gives 3-Methylflavone-8-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Methylflavone-8-carboxylic Acid (CAS 3468-01-7), a certified reference material (molecular formula C17H12O4, MW 280.27 g/mol) for analytical method development and quality control.

The molecular framework of 3-Methylflavone-8-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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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-Methylflavone-8-carboxylic Acid 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.
