Chemical Structure
Description
6-(Naphthalen-1-yl)-2-oxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid (CAS 439094-93-6), molecular formula C15H12N2O3 and molecular weight 268.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(Naphthalen-1-yl)-2-oxo-1,2,3,6-tetrahydropyrimidine-4-carboxylic acid (C15H12N2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. 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.
As a certified reference material (CRM), 6-(Naphthalen-1-yl)-2-oxo-1,2,3,6-tetrahydropyrimidine-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.
