Chemical Structure
Description
Based on its molecular formula C8H10N2O4, 4,5-Dimethoxy-2-nitroaniline contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
4,5-Dimethoxy-2-nitroaniline (CAS 7595-31-5), molecular formula C8H10N2O4 and molecular weight 198.18 g/mol, is a CATO reference standard with documented purity and traceability.
