Chemical Structure
Description
As a certified reference material (CRM), 3',5,7-Trihydroxy 4',5',6-trimethoxyflavone 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.
CATO supplies 3',5,7-Trihydroxy 4',5',6-trimethoxyflavone (CAS 78417-26-2), a certified reference material (molecular formula C18H16O8, MW 360.31 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, 3',5,7-Trihydroxy 4',5',6-trimethoxyflavone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 360.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
