Description

Compared with other compounds in its class, the molecular weight of 521.51 g/mol gives 120225-64-1 4-[2-[[6-Amino-9-(N-ethyl-|A-D-ribofuranuronamidosyl)-9H-purin-2-yl]amino]ethyl]benzenepropanoic Acid Monosodium Salt CGS 21680C Sodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

120225-64-1 4-[2-[[6-Amino-9-(N-ethyl-|A-D-ribofuranuronamidosyl)-9H-purin-2-yl]amino]ethyl]benzenepropanoic Acid Monosodium Salt CGS 21680C Sodium Salt (CAS 120225-64-1) is a high-purity analytical reference standard with the molecular formula C23H28N7O6Na and a molecular weight of 521.51 g/mol.

The molecular framework of 120225-64-1 4-[2-[[6-Amino-9-(N-ethyl-|A-D-ribofuranuronamidosyl)-9H-purin-2-yl]amino]ethyl]benzenepropanoic Acid Monosodium Salt CGS 21680C Sodium Salt (C23H28N7O6Na) 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. 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.
