Compared with other compounds in its class, the molecular weight of 377.23 g/mol gives 4-(3-Bromophenoxy)-2-phenylquinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(3-Bromophenoxy)-2-phenylquinazoline (CAS 866155-23-9), molecular formula C20H13BrN2O and molecular weight 377.23 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 4-(3-Bromophenoxy)-2-phenylquinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 4-(3-Bromophenoxy)-2-phenylquinazoline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
