Chemical Structure
Description
The molecular framework of (S)-2-((tert-Butoxycarbonyl)amino)-3-((tert-butyldiphenylsilyl)oxy)propanoic acid (C24H33NO5Si) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
(S)-2-((tert-Butoxycarbonyl)amino)-3-((tert-butyldiphenylsilyl)oxy)propanoic acid (CAS 145790-51-8), molecular formula C24H33NO5Si and molecular weight 443.61 g/mol, is a CATO reference standard with documented purity and traceability.
