Chemical Structure

(5Z)-5-[(Dimethylamino)methylidene]-4-methyl-3-(4-nitrophenyl)-2,5-dihydrofuran-2-one CAS 338976-32-2 chemical structure

Description

The occurrence of (5Z)-5-[(Dimethylamino)methylidene]-4-methyl-3-(4-nitrophenyl)-2,5-dihydrofuran-2-one 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 (5Z)-5-[(Dimethylamino)methylidene]-4-methyl-3-(4-nitrophenyl)-2,5-dihydrofuran-2-one (CAS 338976-32-2), a certified reference material (molecular formula C14H14N2O4, MW 274.27 g/mol) for analytical method development and quality control.

The molecular framework of (5Z)-5-[(Dimethylamino)methylidene]-4-methyl-3-(4-nitrophenyl)-2,5-dihydrofuran-2-one (C14H14N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
