Description

Compared with other compounds in its class, the molecular weight of 299.28 g/mol gives Methyl 5-cyano-1-(4-methoxyphenyl)-4-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 5-cyano-1-(4-methoxyphenyl)-4-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylate (CAS 339018-17-6) is a high-purity analytical reference standard with the molecular formula C15H13N3O4 and a molecular weight of 299.28 g/mol.

The molecular framework of Methyl 5-cyano-1-(4-methoxyphenyl)-4-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylate (C15H13N3O4) is characterized by a flavonoid core, 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. 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.
