Compared with other compounds in its class, the molecular weight of 325.53 g/mol gives 7545-20-2 N-(2-Hydroxyethyl)-9-octadecenamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7545-20-2 N-(2-Hydroxyethyl)-9-octadecenamide (CAS 7545-20-2), molecular formula C20H39NO2 and molecular weight 325.53 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C20H39NO2, 7545-20-2 N-(2-Hydroxyethyl)-9-octadecenamide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 325.53 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.
