Chemical Structure

Ethyl 4-Bromo-6-methoxy-1,5-naphthyridine-3-carboxylate CAS 724788-64-1 chemical structure

Description

As a certified reference material (CRM), Ethyl 4-Bromo-6-methoxy-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.

Ethyl 4-Bromo-6-methoxy-1,5-naphthyridine-3-carboxylate (CAS 724788-64-1), molecular formula C12H11BrN2O3 and molecular weight 311.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 4-Bromo-6-methoxy-1,5-naphthyridine-3-carboxylate (C12H11BrN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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).

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.
