The occurrence of Dimethyl(3-nitrophenyl)phosphine oxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dimethyl(3-nitrophenyl)phosphine oxide (CAS 26786-59-4) is a high-purity analytical reference standard with the molecular formula C8H10NO3P and a molecular weight of 199.14 g/mol.
Based on its molecular formula C8H10NO3P, Dimethyl(3-nitrophenyl)phosphine oxide contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 199.14 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).
