Chemical Structure
Description
The molecular framework of (E)-[3,3-Dimethyl-1-(2-nitrophenoxy)butan-2-ylidene]amino N-propylcarbamate (C16H23N3O5) 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).
(E)-[3,3-Dimethyl-1-(2-nitrophenoxy)butan-2-ylidene]amino N-propylcarbamate (CAS 478048-92-9), molecular formula C16H23N3O5 and molecular weight 337.37 g/mol, is a CATO reference standard with documented purity and traceability.
