tert-Butyl 4-oxo-1-oxa-9-azaspiro[5.5]undec-2-ene-9-carboxylate (CAS 1346229-50-2) is a high-purity analytical reference standard with the molecular formula C14H21NO4 and a molecular weight of 267.32 g/mol.
The molecular framework of tert-Butyl 4-oxo-1-oxa-9-azaspiro[5.5]undec-2-ene-9-carboxylate (C14H21NO4) 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).
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.
