Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 187.17 g/mol gives Sodium 3-(2-aminophenyl)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sodium 3-(2-aminophenyl)propanoate (CAS 2666-20-8), a certified reference material (molecular formula C9H10NO2Na, MW 187.17 g/mol) for analytical method development and quality control.
The molecular framework of Sodium 3-(2-aminophenyl)propanoate (C9H10NO2Na) is characterized by an amino-acid-derived structure, 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.
