6-Chloro-7-ethoxy-4-phenyl-2H-chromen-2-one CAS 297148-07-3

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, 6-Chloro-7-ethoxy-4-phenyl-2H-chromen-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 300.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

6-Chloro-7-ethoxy-4-phenyl-2H-chromen-2-one (CAS 297148-07-3), molecular formula C17H13ClO3 and molecular weight 300.74 g/mol, is a CATO reference standard with documented purity and traceability.

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-Chloro-7-ethoxy-4-phenyl-2H-chromen-2-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.
