(2R,3R)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(4-(trifluoromethyl)phenyl)propanoic acid (CAS 1391405-82-5), molecular formula C25H20F3NO5 and molecular weight 471.43 g/mol, is a CATO reference standard with documented purity and traceability.
(2R,3R)-3-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-2-hydroxy-3-(4-(trifluoromethyl)phenyl)propanoic acid (C25H20F3NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
