CATO supplies 1-(1-(3-(Pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)-3-(3-(trifluoromethyl)phenyl)urea (CAS 1396795-05-3), a certified reference material (molecular formula C21H20F3N5O2, MW 431.41 g/mol) for analytical method development and quality control.
Structurally, 1-(1-(3-(Pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)-3-(3-(trifluoromethyl)phenyl)urea (C21H20F3N5O2) 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 431.41 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.
