Chemical Structure

Ethyl 6-methyl-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate CAS 5000-81-7 chemical structure

Description

The occurrence of Ethyl 6-methyl-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 6-methyl-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate (CAS 5000-81-7) is a high-purity analytical reference standard with the molecular formula C12H12N2O3 and a molecular weight of 232.24 g/mol.

The molecular framework of Ethyl 6-methyl-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate (C12H12N2O3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Ethyl 6-methyl-4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate 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.
