tert-Butyl 2,3-dihydro-5H-spiro[benzo[b][1,4,5]oxathiazocine-4,4'-piperidine]-1'-carboxylate 1,1-dioxide (CAS 1251004-16-6) is a high-purity analytical reference standard with the molecular formula C18H26N2O5S and a molecular weight of 382.47 g/mol.
Structurally, tert-Butyl 2,3-dihydro-5H-spiro[benzo[b][1,4,5]oxathiazocine-4,4'-piperidine]-1'-carboxylate 1,1-dioxide (C18H26N2O5S) contains a flavonoid core, an amide group, a sulfone 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 382.47 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
