Ethyl 5-amino-1,6-naphthyridine-8-carboxylate CAS 1609558-89-5

Description

Compared with other compounds in its class, the molecular weight of 217.22 g/mol gives Ethyl 5-amino-1,6-naphthyridine-8-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 5-amino-1,6-naphthyridine-8-carboxylate (CAS 1609558-89-5), molecular formula C11H11N3O2 and molecular weight 217.22 g/mol, is a CATO reference standard with documented purity and traceability.

Ethyl 5-amino-1,6-naphthyridine-8-carboxylate (C11H11N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
