Chemical Structure
Description
Based on its molecular formula C16H23N3O2, Primaquine Impurity 1 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 289.37 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).
Primaquine Impurity 1 (CAS 47136-26-5) is a certified pharmaceutical impurity reference standard with the molecular formula C16H23N3O2 and a molecular weight of 289.37 g/mol.
