Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-Bromo-3-fluorophenyl)(4-methoxyphenyl)methanone.
(4-Bromo-3-fluorophenyl)(4-methoxyphenyl)methanone (CAS 760192-85-6), molecular formula C14H10BrFO2 and molecular weight 309.13 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Bromo-3-fluorophenyl)(4-methoxyphenyl)methanone (C14H10BrFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine 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 309.13 g/mol, it falls into the moderately-high-molecular-weight range. 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.
