(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-((diphenyl(p-tolyl)methyl)amino)butanoic acid CAS 1217809-38-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 596.71 g/mol gives (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-((diphenyl(p-tolyl)methyl)amino)butanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-((diphenyl(p-tolyl)methyl)amino)butanoic acid (CAS 1217809-38-5), a certified reference material (molecular formula C39H36N2O4, MW 596.71 g/mol) for analytical method development and quality control.

The molecular framework of (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-((diphenyl(p-tolyl)methyl)amino)butanoic acid (C39H36N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
