Description

Compared with other compounds in its class, the molecular weight of 287.23 g/mol gives 2,5-Dioxopyrrolidin-1-yl 4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,5-Dioxopyrrolidin-1-yl 4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate (CAS 5442-69-3), a certified reference material (molecular formula C13H9N3O5, MW 287.23 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2,5-Dioxopyrrolidin-1-yl 4-oxo-1,4-dihydro-1,5-naphthyridine-3-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 2,5-Dioxopyrrolidin-1-yl 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.
