Chemical Structure
Description
6-Methoxy-2-(pyridin-2-yl)quinoline-5,8-dione (CAS 60582-46-9), molecular formula C15H10N2O3 and molecular weight 266.25 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Methoxy-2-(pyridin-2-yl)quinoline-5,8-dione (C15H10N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 266.25 g/mol, it falls into the medium-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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
