Chemical Structure

(2R,3S)-2,3-diaminosuccinic acid CAS 23220-52-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (2R,3S)-2,3-diaminosuccinic acid (CAS 23220-52-2), a certified reference material (molecular formula C4H8N2O4, MW 148.12 g/mol) for analytical method development and quality control.

The molecular framework of (2R,3S)-2,3-diaminosuccinic acid (C4H8N2O4) is characterized by a carbohydrate-derived structure, an amide group. 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.

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.
