(S)-3-(((2S,3R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)butanoyl)oxy)-2-((tert-butoxycarbonyl)amino)propanoic acid (CAS 944283-12-9), molecular formula C31H40N2O9 and molecular weight 584.66 g/mol, is a CATO reference standard with documented purity and traceability.
(S)-3-(((2S,3R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)butanoyl)oxy)-2-((tert-butoxycarbonyl)amino)propanoic acid (C31H40N2O9) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
As a certified reference material (CRM), (S)-3-(((2S,3R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(tert-butoxy)butanoyl)oxy)-2-((tert-butoxycarbonyl)amino)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
