Chemical Structure

2-Methyl-1,6-naphthyridin-5(6H)-one CAS 80812-67-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2-Methyl-1,6-naphthyridin-5(6H)-one (CAS 80812-67-5) is a high-purity analytical reference standard with the molecular formula C9H8N2O and a molecular weight of 160.17 g/mol.

The molecular framework of 2-Methyl-1,6-naphthyridin-5(6H)-one (C9H8N2O) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
