As a certified reference material (CRM), 9,9-Difluoro-2-azaspiro[5.5]undecane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
9,9-Difluoro-2-azaspiro[5.5]undecane (CAS 1638761-33-7) is a high-purity analytical reference standard with the molecular formula C10H17F2N and a molecular weight of 189.25 g/mol.
9,9-Difluoro-2-azaspiro[5.5]undecane (C10H17F2N) contains a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
