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 3-Bromo-2-(4-fluorophenyl)acetophenone.
CATO supplies 3-Bromo-2-(4-fluorophenyl)acetophenone (CAS 898784-71-9), a certified reference material (molecular formula C14H10BrFO, MW 293.13 g/mol) for analytical method development and quality control.
3-Bromo-2-(4-fluorophenyl)acetophenone (C14H10BrFO) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
