2-((4-(4-Fluorophenyl)piperazin-1-yl)methyl)-2,3-dihydroimidazo[1,2-c]quinazolin-5(1H)-one (CAS 145938-41-6), molecular formula C21H22FN5O and molecular weight 379.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((4-(4-Fluorophenyl)piperazin-1-yl)methyl)-2,3-dihydroimidazo[1,2-c]quinazolin-5(1H)-one (C21H22FN5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 379.43 g/mol, it falls into the moderately-high-molecular-weight range. 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.
