Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 262.10 g/mol gives 6-Bromo-1H-benzo[de]quinolin-2(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Bromo-1H-benzo[de]quinolin-2(3H)-one (CAS 2767589-82-0), molecular formula C12H8BrNO and molecular weight 262.10 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Bromo-1H-benzo[de]quinolin-2(3H)-one (C12H8BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 262.10 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
