1-[(2-Fluorobenzyl)oxy]-3-(2-methylbenzyl)-1H-imidazole-2,4,5(3H)-trione (CAS 303986-60-9), molecular formula C18H15FN2O4 and molecular weight 342.32 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-[(2-Fluorobenzyl)oxy]-3-(2-methylbenzyl)-1H-imidazole-2,4,5(3H)-trione (C18H15FN2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 342.32 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
