Chemical Structure
Description
The molecular framework of 3-(4-Nitrophenoxy)aniline (C12H10N2O3) is characterized by an amino-acid-derived structure, 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).
3-(4-Nitrophenoxy)aniline (CAS 22528-34-3) is a high-purity analytical reference standard with the molecular formula C12H10N2O3 and a molecular weight of 230.22 g/mol.
