Chemical Structure

6-Fluoro-2-(3-fluorophenyl)-4H-chromen-4-one CAS 213894-70-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Fluoro-2-(3-fluorophenyl)-4H-chromen-4-one.

CATO supplies 6-Fluoro-2-(3-fluorophenyl)-4H-chromen-4-one (CAS 213894-70-3), a certified reference material (molecular formula C15H8F2O2, MW 258.22 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 6-Fluoro-2-(3-fluorophenyl)-4H-chromen-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.22 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), 6-Fluoro-2-(3-fluorophenyl)-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.
