Chemical Structure
Description
The molecular framework of (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3,4,5-trimethoxyphenyl)acetic acid (C26H25NO7) 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).
(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(3,4,5-trimethoxyphenyl)acetic acid (CAS 1260593-19-8), molecular formula C26H25NO7 and molecular weight 463.48 g/mol, is a CATO reference standard with documented purity and traceability.
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.
