Chemical Structure
Description
As a certified reference material (CRM), 2-(4-Bromopyridin-2-yl)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.
2-(4-Bromopyridin-2-yl)oxazole (CAS 1243363-48-5) is a high-purity analytical reference standard with the molecular formula C8H5BrN2O and a molecular weight of 225.04 g/mol.
2-(4-Bromopyridin-2-yl)oxazole (C8H5BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
