Chemical Structure

(R)-2-Amino-3-((7-sulfamoylbenzo[c][1,2,5]oxadiazol-4-yl)thio)propanoic acid CAS 91366-71-1 chemical structure

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)-2-Amino-3-((7-sulfamoylbenzo[c][1,2,5]oxadiazol-4-yl)thio)propanoic acid (CAS 91366-71-1) is a high-purity analytical reference standard with the molecular formula C9H10N4O5S2 and a molecular weight of 318.33 g/mol.

The molecular framework of (R)-2-Amino-3-((7-sulfamoylbenzo[c][1,2,5]oxadiazol-4-yl)thio)propanoic acid (C9H10N4O5S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
