Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(2R,3R)-3-((tert-butoxycarbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid (CAS 1217602-85-1) is a high-purity analytical reference standard with the molecular formula C18H21NO5 and a molecular weight of 331.36 g/mol.
The molecular framework of (2R,3R)-3-((tert-butoxycarbonyl)amino)-2-hydroxy-3-(naphthalen-2-yl)propanoic acid (C18H21NO5) 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).
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.
