Compared with other compounds in its class, the molecular weight of 366.71 g/mol gives 2,6,10,14,18-Pentamethylheneicosane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,6,10,14,18-Pentamethylheneicosane (CAS 66519-77-5), a certified reference material (molecular formula C26H54, MW 366.71 g/mol) for analytical method development and quality control.
Based on its molecular formula C26H54, 2,6,10,14,18-Pentamethylheneicosane contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 366.71 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.
