2-Amino-4-(6-oxo-1H-purin-9(6H)-yl)butanoic acid (CAS 25643-89-4), molecular formula C50H101N2O6CH3O4S and molecular weight 937.46 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C50H101N2O6CH3O4S, 2-Amino-4-(6-oxo-1H-purin-9(6H)-yl)butanoic acid contains an amide group, a sulfone 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 937.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
