CATO supplies (2S,5R)-2,5-Dihydro-3,6-dimethoxy-2-[(2S)-2-[[4-methoxy-3-(3-methoxypropoxy)phenyl]methyl]-3-methylbutyl]-5-(1-methylethyl)pyrazine (CAS 656241-17-7), a certified reference material (molecular formula C26H42N2O5, MW 462.62 g/mol) for analytical method development and quality control.
Based on its molecular formula C26H42N2O5, (2S,5R)-2,5-Dihydro-3,6-dimethoxy-2-[(2S)-2-[[4-methoxy-3-(3-methoxypropoxy)phenyl]methyl]-3-methylbutyl]-5-(1-methylethyl)pyrazine contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 462.62 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
