CATO supplies (+/-)-3-Octadecanamido-1,2-propanediol (+/-)-N-(2,3-Dihydroxypropyl)octadecanamide 7336-25-6 rac N-(2,3-Dihydroxypropyl)octadecanamide (CAS 7336-25-6), a certified reference material (molecular formula C21H43NO3, MW 357.57 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H43NO3, (+/-)-3-Octadecanamido-1,2-propanediol (+/-)-N-(2,3-Dihydroxypropyl)octadecanamide 7336-25-6 rac N-(2,3-Dihydroxypropyl)octadecanamide 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 357.57 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.
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.
