1-(4-Bromophenyl)-1,1-difluoropropan-2-one CAS 897934-99-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-Bromophenyl)-1,1-difluoropropan-2-one.

CATO supplies 1-(4-Bromophenyl)-1,1-difluoropropan-2-one (CAS 897934-99-5), a certified reference material (molecular formula C9H7BrF2O, MW 249.05 g/mol) for analytical method development and quality control.

The molecular framework of 1-(4-Bromophenyl)-1,1-difluoropropan-2-one (C9H7BrF2O) is characterized by a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
