2-(4-Bromophenyl)-4-phenylquinazoline CAS 540466-42-0

Description

Compared with other compounds in its class, the molecular weight of 361.23 g/mol gives 2-(4-Bromophenyl)-4-phenylquinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-(4-Bromophenyl)-4-phenylquinazoline (CAS 540466-42-0), a certified reference material (molecular formula C20H13BrN2, MW 361.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 2-(4-Bromophenyl)-4-phenylquinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 2-(4-Bromophenyl)-4-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.
