Tert-butyl 3-thia-9-azaspiro[5.5]Undecane-9-carboxylate (CAS 1782319-83-8), molecular formula C14H25NO2S and molecular weight 271.42 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H25NO2S, Tert-butyl 3-thia-9-azaspiro[5.5]Undecane-9-carboxylate contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 271.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
