3,5-Diethyl 6-[4-(4-methoxyphenyl)piperazin-1-yl]-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate CAS 338396-57-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 429.47 g/mol gives 3,5-Diethyl 6-[4-(4-methoxyphenyl)piperazin-1-yl]-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3,5-Diethyl 6-[4-(4-methoxyphenyl)piperazin-1-yl]-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate (CAS 338396-57-9) is a high-purity analytical reference standard with the molecular formula C22H27N3O6 and a molecular weight of 429.47 g/mol.

The molecular framework of 3,5-Diethyl 6-[4-(4-methoxyphenyl)piperazin-1-yl]-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate (C22H27N3O6) 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.

As a certified reference material (CRM), 3,5-Diethyl 6-[4-(4-methoxyphenyl)piperazin-1-yl]-2-oxo-1,2-dihydropyridine-3,5-dicarboxylate 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.
