Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 224.05 g/mol gives 5-(3-Bromophenyl)oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-(3-Bromophenyl)oxazole (CAS 243455-57-4), molecular formula C9H6BrNO and molecular weight 224.05 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H6BrNO, 5-(3-Bromophenyl)oxazole contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 224.05 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 5-(3-Bromophenyl)oxazole 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.
