1-(4-Chloro-3-fluorophenyl)-3-(4-fluorophenyl)propan-1-one CAS 898768-46-2

Description

The occurrence of 1-(4-Chloro-3-fluorophenyl)-3-(4-fluorophenyl)propan-1-one 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.

1-(4-Chloro-3-fluorophenyl)-3-(4-fluorophenyl)propan-1-one (CAS 898768-46-2) is a high-purity analytical reference standard with the molecular formula C15H11ClF2O and a molecular weight of 280.70 g/mol.

Structurally, 1-(4-Chloro-3-fluorophenyl)-3-(4-fluorophenyl)propan-1-one (C15H11ClF2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 280.70 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
