Chemical Structure
Description
3-(Bromomethyl)-4-methylquinolin-2(1H)-one (CAS 91348-38-8), molecular formula C22H22F2N2O10 and molecular weight 512.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Bromomethyl)-4-methylquinolin-2(1H)-one (C22H22F2N2O10) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 512.41 g/mol, it falls into the moderately-high-molecular-weight range. 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-(Bromomethyl)-4-methylquinolin-2(1H)-one 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.
