Chemical Structure
Description
6-Bromo-3-ethyl-1-methyl-3,4-dihydroquinoxalin-2(1H)-one (C11H13BrN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
6-Bromo-3-ethyl-1-methyl-3,4-dihydroquinoxalin-2(1H)-one (CAS 1499036-47-3), molecular formula C11H13BrN2O and molecular weight 269.14 g/mol, is a CATO reference standard with documented purity and traceability.
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.
