(R)-3-(1H-Indol-3-yl)-2-((3-sulfopropyl)amino)propanoic acid CAS 819864-30-7

Description

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.

(R)-3-(1H-Indol-3-yl)-2-((3-sulfopropyl)amino)propanoic acid (CAS 819864-30-7) is a high-purity analytical reference standard with the molecular formula C14H18N2O5S and a molecular weight of 326.37 g/mol.

The molecular framework of (R)-3-(1H-Indol-3-yl)-2-((3-sulfopropyl)amino)propanoic acid (C14H18N2O5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
