Compared with other compounds in its class, the molecular weight of 279.14 g/mol gives 3-Methyl-3H-imidazo[4,5-f]quinolin-2-amine hydrobromide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Methyl-3H-imidazo[4,5-f]quinolin-2-amine hydrobromide (CAS 83407-39-0), molecular formula C11H10N4HBr and molecular weight 279.14 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methyl-3H-imidazo[4,5-f]quinolin-2-amine hydrobromide (C11H10N4HBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), 3-Methyl-3H-imidazo[4,5-f]quinolin-2-amine hydrobromide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
