188011-69-0 4-[(5-bromopyridin-2-yl)amino]-4-oxobutanoic acid N-(5-Bromo-pyridin-2-yl)-succinamic acid n-(5-bromopyridin-2-yl)succinamic acid (CAS 188011-69-0), molecular formula C9H9BrN2O3 and molecular weight 273.08 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 188011-69-0 4-[(5-bromopyridin-2-yl)amino]-4-oxobutanoic acid N-(5-Bromo-pyridin-2-yl)-succinamic acid n-(5-bromopyridin-2-yl)succinamic acid (C9H9BrN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
