Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 218.09 g/mol gives 2-(bromomethyl)-5-(tert-butyl)oxazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(bromomethyl)-5-(tert-butyl)oxazole (CAS 1334492-54-4), a certified reference material (molecular formula C8H12BrNO, MW 218.09 g/mol) for analytical method development and quality control.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, 2-(bromomethyl)-5-(tert-butyl)oxazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.09 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-(bromomethyl)-5-(tert-butyl)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.
