Compared with other compounds in its class, the molecular weight of 268.52 g/mol gives N-Nonadecane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N-Nonadecane (CAS 629-92-5), molecular formula C19H40 and molecular weight 268.52 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H40, N-Nonadecane contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 268.52 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.
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.
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.
