Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 333.22 g/mol gives 9-(4-Bromophenyl)anthracene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 9-(4-Bromophenyl)anthracene (CAS 24672-71-7), a certified reference material (molecular formula C20H13Br, MW 333.22 g/mol) for analytical method development and quality control.
9-(4-Bromophenyl)anthracene (C20H13Br) contains 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 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.
