6-Chloroquinoline-2,3-dicarboxylic acid (CAS 92513-50-3) is a high-purity analytical reference standard with the molecular formula C11H6ClNO4 and a molecular weight of 251.62 g/mol.
Based on its molecular formula C11H6ClNO4, 6-Chloroquinoline-2,3-dicarboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 251.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
