(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-hydroxyphenyl)-2-methylpropanoic acid (CAS 246539-83-3) is a high-purity analytical reference standard with the molecular formula C25H23NO5 and a molecular weight of 417.45 g/mol.
(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(4-hydroxyphenyl)-2-methylpropanoic acid (C25H23NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
