Chemical Structure

(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-dichlorophenyl)acetic acid CAS 1260605-33-1 chemical structure

Description

The occurrence of (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-dichlorophenyl)acetic acid is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-dichlorophenyl)acetic acid (CAS 1260605-33-1), a certified reference material (molecular formula C23H17Cl2NO4, MW 442.29 g/mol) for analytical method development and quality control.

The molecular framework of (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-(2,3-dichlorophenyl)acetic acid (C23H17Cl2NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
