Compared with other compounds in its class, the molecular weight of 321.37 g/mol gives (R)-methyl 2-((tert-butoxycarbonyl)amino)-5-oxo-5-phenylpentanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-methyl 2-((tert-butoxycarbonyl)amino)-5-oxo-5-phenylpentanoate (CAS 128811-49-4), molecular formula C17H23NO5 and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-methyl 2-((tert-butoxycarbonyl)amino)-5-oxo-5-phenylpentanoate (C17H23NO5) 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 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.
