Description
As a certified reference material (CRM), 6,8-Dichloro-2-(pyridin-3-yl)quinoline-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
6,8-Dichloro-2-(pyridin-3-yl)quinoline-4-carboxylic acid (CAS 67059-24-9) is a high-purity analytical reference standard with the molecular formula C15H8Cl2N2O2 and a molecular weight of 319.14 g/mol.
Structurally, 6,8-Dichloro-2-(pyridin-3-yl)quinoline-4-carboxylic acid (C15H8Cl2N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 319.14 g/mol, it falls into the moderately-high-molecular-weight range. 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.
