Chemical Structure
Description
As a certified reference material (CRM), (R)-2-((tert-Butoxycarbonyl)amino)-3-(4-((tert-butoxycarbonyl)oxy)phenyl)propanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(R)-2-((tert-Butoxycarbonyl)amino)-3-(4-((tert-butoxycarbonyl)oxy)phenyl)propanoic acid (CAS 1241677-97-3), molecular formula C19H27NO7 and molecular weight 381.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-2-((tert-Butoxycarbonyl)amino)-3-(4-((tert-butoxycarbonyl)oxy)phenyl)propanoic acid (C19H27NO7) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
