2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(dimethylamino)butanoic acid hydrochloride CAS 2137488-99-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 404.89 g/mol gives 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(dimethylamino)butanoic acid hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(dimethylamino)butanoic acid hydrochloride (CAS 2137488-99-2) is a high-purity analytical reference standard with the molecular formula C21H24N2O4HCl and a molecular weight of 404.89 g/mol.

The molecular framework of 2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-4-(dimethylamino)butanoic acid hydrochloride (C21H24N2O4HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
