Chemical Structure
Description
Tert-butyl 7-oxo-2-azaspiro[5.5]Undecane-2-carboxylate (C15H25NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
Tert-butyl 7-oxo-2-azaspiro[5.5]Undecane-2-carboxylate (CAS 1781844-06-1) is a high-purity analytical reference standard with the molecular formula C15H25NO3 and a molecular weight of 267.36 g/mol.
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.
