Chemical Structure

(S)-2-Amino-5-(((S)-1-carboxy-2-(3,4-dihydroxyphenyl)ethyl)amino)-5-oxopentanoic acid CAS 52370-58-8 chemical structure

Description

The occurrence of (S)-2-Amino-5-(((S)-1-carboxy-2-(3,4-dihydroxyphenyl)ethyl)amino)-5-oxopentanoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-2-Amino-5-(((S)-1-carboxy-2-(3,4-dihydroxyphenyl)ethyl)amino)-5-oxopentanoic acid (CAS 52370-58-8), a certified reference material (molecular formula C14H18N2O7, MW 326.30 g/mol) for analytical method development and quality control.

(S)-2-Amino-5-(((S)-1-carboxy-2-(3,4-dihydroxyphenyl)ethyl)amino)-5-oxopentanoic acid (C14H18N2O7) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.

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.
