(2S,6S)-11-bromo-2-hydroxy-1,7-diazatricyclo[7.3.0.0²,⁶]dodeca-9,11-dien-8-one (CAS 2691863-80-4), molecular formula C10H11BrN2O2 and molecular weight 271.11 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H11BrN2O2, (2S,6S)-11-bromo-2-hydroxy-1,7-diazatricyclo[7.3.0.0²,⁶]dodeca-9,11-dien-8-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 271.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
