Ethyl 2-(2-oxo-3-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)pyridin-1(2H)-yl)acetate CAS 1396848-32-0 chemical structure

Description

The occurrence of Ethyl 2-(2-oxo-3-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)pyridin-1(2H)-yl)acetate is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-(2-oxo-3-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)pyridin-1(2H)-yl)acetate (CAS 1396848-32-0) is a high-purity analytical reference standard with the molecular formula C16H14N4O4 and a molecular weight of 326.31 g/mol.

Structurally, Ethyl 2-(2-oxo-3-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)pyridin-1(2H)-yl)acetate (C16H14N4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 326.31 g/mol, it falls into the moderately-high-molecular-weight range. 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.
