Chemical Structure
Description
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.
CATO supplies 9-Fluoro-3-azaspiro[5.5]Undecane (CAS 1781296-68-1), a certified reference material (molecular formula C10H18FN, MW 171.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H18FN, 9-Fluoro-3-azaspiro[5.5]Undecane contains a nitrile group, fluorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 171.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
