Chemical Structure
Description
Tert-butyl 5-fluoro-1,9-diazaspiro[5.5]Undecane-9-carboxylate (C14H25FN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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 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).
Tert-butyl 5-fluoro-1,9-diazaspiro[5.5]Undecane-9-carboxylate (CAS 1889136-73-5) is a high-purity analytical reference standard with the molecular formula C14H25FN2O2 and a molecular weight of 272.36 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.
