2-(4-Bromophenyl)-5'-fluoro-2'-hydroxyacetophenone CAS 527751-51-5

Description

The occurrence of 2-(4-Bromophenyl)-5'-fluoro-2'-hydroxyacetophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(4-Bromophenyl)-5'-fluoro-2'-hydroxyacetophenone (CAS 527751-51-5) is a high-purity analytical reference standard with the molecular formula C14H10BrFO2 and a molecular weight of 309.13 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system, 2-(4-Bromophenyl)-5'-fluoro-2'-hydroxyacetophenone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
