4-Chloro-9-iodo-5,11-dihydrobenzo[b]pyrido[2,3-e][1,4]oxazepine (CAS 2834080-78-1), molecular formula C12H8ClIN2O and molecular weight 358.56 g/mol, is a CATO reference standard with documented purity and traceability.
4-Chloro-9-iodo-5,11-dihydrobenzo[b]pyrido[2,3-e][1,4]oxazepine (C12H8ClIN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine 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.
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.
