(S)-2-Amino-5-(((R)-1-((carboxymethyl)amino)-1-oxo-3-(sulfothio)propan-2-yl)amino)-5-oxopentanoic acid CAS 1637-70-3

Description

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.

(S)-2-Amino-5-(((R)-1-((carboxymethyl)amino)-1-oxo-3-(sulfothio)propan-2-yl)amino)-5-oxopentanoic acid (CAS 1637-70-3) is a high-purity analytical reference standard with the molecular formula C10H17N3O9S2 and a molecular weight of 387.39 g/mol.

(S)-2-Amino-5-(((R)-1-((carboxymethyl)amino)-1-oxo-3-(sulfothio)propan-2-yl)amino)-5-oxopentanoic acid (C10H17N3O9S2) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
