tert-Butyl 7-ethynyl-2-azaspiro[3.5]nonane-2-carboxylate (CAS 1434142-19-4) is a high-purity analytical reference standard with the molecular formula C15H23NO2 and a molecular weight of 249.35 g/mol.
tert-Butyl 7-ethynyl-2-azaspiro[3.5]nonane-2-carboxylate (C15H23NO2) 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).
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.
