1-(3-(2-(4-Nitrobenzamido)ethyl)-1H-indol-2-yl)pyridin-1-ium bromide (CAS 1291072-38-2), molecular formula C22H19N4O3Br and molecular weight 467.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(3-(2-(4-Nitrobenzamido)ethyl)-1H-indol-2-yl)pyridin-1-ium bromide (C22H19N4O3Br) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
