Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-(Naphthalen-2-yl)picolinic acid (CAS 811470-25-4) is a high-purity analytical reference standard with the molecular formula C18H12N2O4 and a molecular weight of 320.30 g/mol.
6-(Naphthalen-2-yl)picolinic acid (C18H12N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), 6-(Naphthalen-2-yl)picolinic 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.
