Description
Compared with other compounds in its class, the molecular weight of 294.74 g/mol gives 2-(4-Chlorophenyl)-1H,2H,3H-pyrrolo[3,4-b]quinolin-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-Chlorophenyl)-1H,2H,3H-pyrrolo[3,4-b]quinolin-1-one (CAS 180161-75-5), molecular formula C17H11ClN2O and molecular weight 294.74 g/mol, is a CATO reference standard with documented purity and traceability.
2-(4-Chlorophenyl)-1H,2H,3H-pyrrolo[3,4-b]quinolin-1-one (C17H11ClN2O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
