(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-ureidophenyl)propanoic acid (CAS 324017-23-4) is a high-purity analytical reference standard with the molecular formula C25H23N3O5 and a molecular weight of 445.47 g/mol.
(S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-ureidophenyl)propanoic acid (C25H23N3O5) contains a flavonoid core, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (S)-2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-ureidophenyl)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
