CATO supplies (3S,8s,9s,10r,13r,14s,17r)-10,13-dimethyl-17-((r)-6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1h-cyclopenta[a]phenanthren-3-yl dodecyl carbonate (CAS 15455-85-3), a certified reference material (molecular formula C40H70O3, MW 598.98 g/mol) for analytical method development and quality control.
Based on its molecular formula C40H70O3, (3S,8s,9s,10r,13r,14s,17r)-10,13-dimethyl-17-((r)-6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1h-cyclopenta[a]phenanthren-3-yl dodecyl carbonate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 598.98 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
