tert-Butyl 5-oxo-9-oxa-2-azaspiro[5.5]undecane-2-carboxylate (CAS 2179071-32-8) is a high-purity analytical reference standard with the molecular formula C14H23NO4 and a molecular weight of 269.34 g/mol.
tert-Butyl 5-oxo-9-oxa-2-azaspiro[5.5]undecane-2-carboxylate (C14H23NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
