Chemical Structure
Description
The occurrence of 2-(((2-Methoxy-4-nitrophenyl)amino)methylene)-5,5-dimethylcyclohexane-1,3-dione 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.
CATO supplies 2-(((2-Methoxy-4-nitrophenyl)amino)methylene)-5,5-dimethylcyclohexane-1,3-dione (CAS 330215-30-0), a certified reference material (molecular formula C16H18N2O5, MW 318.32 g/mol) for analytical method development and quality control.
The molecular framework of 2-(((2-Methoxy-4-nitrophenyl)amino)methylene)-5,5-dimethylcyclohexane-1,3-dione (C16H18N2O5) 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).
