Chemical Structure

3,4-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone CAS 898778-58-0 chemical structure

Description

The occurrence of 3,4-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone 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-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone (CAS 898778-58-0) is a high-purity analytical reference standard with the molecular formula C15H9Cl2F3O and a molecular weight of 333.13 g/mol.

The molecular framework of 3,4-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone (C15H9Cl2F3O) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3,4-Dichloro-3-(3,4,5-trifluorophenyl)-propiophenone 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.
