(R,E)-6-((3,7-Dimethylocta-2,6-dien-1-yl)oxy)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (CAS 187235-55-8), molecular formula C16H23N3O4 and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H23N3O4, (R,E)-6-((3,7-Dimethylocta-2,6-dien-1-yl)oxy)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
