Chemical Structure
Description
3-(3-bromopropyl)-5-nitro-2,3-dihydro-1,3-benzoxazol-2-one (CAS 1157079-54-3) is a high-purity analytical reference standard with the molecular formula C10H9BrN2O4 and a molecular weight of 301.09 g/mol.
Based on its molecular formula C10H9BrN2O4, 3-(3-bromopropyl)-5-nitro-2,3-dihydro-1,3-benzoxazol-2-one 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 301.09 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
