(4-Bromophenyl)(3-fluorophenyl)methanone CAS 951885-68-0

Description

Compared with other compounds in its class, the molecular weight of 279.10 g/mol gives (4-Bromophenyl)(3-fluorophenyl)methanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(4-Bromophenyl)(3-fluorophenyl)methanone (CAS 951885-68-0) is a high-purity analytical reference standard with the molecular formula C13H8BrFO and a molecular weight of 279.10 g/mol.

Structurally, (4-Bromophenyl)(3-fluorophenyl)methanone (C13H8BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring 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 279.10 g/mol, it falls into the medium-molecular-weight range. 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.

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.
