N-(4-(5-Oxo-4,5-dihydropyrazin-2-yl)phenyl)isonicotinamide CAS 89541-68-4

Description

The occurrence of N-(4-(5-Oxo-4,5-dihydropyrazin-2-yl)phenyl)isonicotinamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-(4-(5-Oxo-4,5-dihydropyrazin-2-yl)phenyl)isonicotinamide (CAS 89541-68-4), a certified reference material (molecular formula C16H12N4O2, MW 292.29 g/mol) for analytical method development and quality control.

N-(4-(5-Oxo-4,5-dihydropyrazin-2-yl)phenyl)isonicotinamide (C16H12N4O2) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
