Chemical Structure

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid CAS 1956434-67-5 chemical structure

Description

The occurrence of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid (CAS 1956434-67-5), molecular formula C21H18N2O5 and molecular weight 378.38 g/mol, is a CATO reference standard with documented purity and traceability.

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-3-(oxazol-5-yl)propanoic acid (C21H18N2O5) 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 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).
