3-Bromo-4-[(3-methyl-1,2-oxazol-5-yl)methoxy]benzoic acid (CAS 1221724-03-3), molecular formula C12H10BrNO4 and molecular weight 312.12 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-4-[(3-methyl-1,2-oxazol-5-yl)methoxy]benzoic acid (C12H10BrNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
