Compared with other compounds in its class, the molecular weight of 322.04 g/mol gives 1-Bromo-4-((5-bromopentyl)oxy)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromo-4-((5-bromopentyl)oxy)benzene (CAS 91130-83-5), molecular formula C11H14Br2O and molecular weight 322.04 g/mol, is a CATO reference standard with documented purity and traceability.
1-Bromo-4-((5-bromopentyl)oxy)benzene (C11H14Br2O) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring 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. 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.
