3-(4-Chloro-3-methylphenoxy)-7-hydroxy-2-(trifluoromethyl)-4H-chromen-4-one CAS 691366-79-7 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 3-(4-Chloro-3-methylphenoxy)-7-hydroxy-2-(trifluoromethyl)-4H-chromen-4-one.

CATO supplies 3-(4-Chloro-3-methylphenoxy)-7-hydroxy-2-(trifluoromethyl)-4H-chromen-4-one (CAS 691366-79-7), a certified reference material (molecular formula C17H10ClF3O4, MW 370.71 g/mol) for analytical method development and quality control.

Based on its molecular formula C17H10ClF3O4, 3-(4-Chloro-3-methylphenoxy)-7-hydroxy-2-(trifluoromethyl)-4H-chromen-4-one contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 370.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(4-Chloro-3-methylphenoxy)-7-hydroxy-2-(trifluoromethyl)-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.
