The occurrence of 4-Bromooxazolo[4,5-c]pyridin-2(3H)-one is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromooxazolo[4,5-c]pyridin-2(3H)-one (CAS 1936731-52-0) is a high-purity analytical reference standard with the molecular formula C6H3BrN2O2 and a molecular weight of 215.00 g/mol.
Based on its molecular formula C6H3BrN2O2, 4-Bromooxazolo[4,5-c]pyridin-2(3H)-one contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.00 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
