2-Oxo-1,2-dihydro-1,6-naphthyridine-3-carboxylic acid CAS 219849-79-3

Description

Compared with other compounds in its class, the molecular weight of 190.16 g/mol gives 2-Oxo-1,2-dihydro-1,6-naphthyridine-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Oxo-1,2-dihydro-1,6-naphthyridine-3-carboxylic acid (CAS 219849-79-3), molecular formula C9H6N2O3 and molecular weight 190.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Oxo-1,2-dihydro-1,6-naphthyridine-3-carboxylic acid (C9H6N2O3) is characterized by an amino-acid-derived structure, 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.

CATO manufactures 2-Oxo-1,2-dihydro-1,6-naphthyridine-3-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
