1'-tert-Butyl 2-ethyl 6,8-dihydrospiro[[1,2,4]triazolo[5,1-c][1,4]oxazine-5,4'-piperidine]-1',2-dicarboxylate (CAS 1273567-97-7), molecular formula C17H26N4O5 and molecular weight 366.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1'-tert-Butyl 2-ethyl 6,8-dihydrospiro[[1,2,4]triazolo[5,1-c][1,4]oxazine-5,4'-piperidine]-1',2-dicarboxylate (C17H26N4O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 366.41 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
