Chemical Structure
Description
The molecular framework of tert-Butyl 9-oxo-1-oxa-4-azaspiro[5.5]undecane-4-carboxylate (C14H23NO4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
tert-Butyl 9-oxo-1-oxa-4-azaspiro[5.5]undecane-4-carboxylate (CAS 1251012-92-6) is a high-purity analytical reference standard with the molecular formula C14H23NO4 and a molecular weight of 269.34 g/mol.
