3-(4-Chlorophenyl)-2,4-difluoropropiophenone CAS 654673-29-7

Description

The occurrence of 3-(4-Chlorophenyl)-2,4-difluoropropiophenone is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(4-Chlorophenyl)-2,4-difluoropropiophenone (CAS 654673-29-7), molecular formula C15H11ClF2O and molecular weight 280.70 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system, 3-(4-Chlorophenyl)-2,4-difluoropropiophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.70 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.

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-Chlorophenyl)-2,4-difluoropropiophenone 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.
