Chemical Structure

L-Ornithine L-Aspartate CAS 3230-94-2 chemical structure

Description

CATO supplies L-Ornithine L-Aspartate (CAS 3230-94-2), a certified reference material (molecular formula C4H7NO4C5H12N2O2, MW 265.27 g/mol) for analytical method development and quality control.

The molecular framework of L-Ornithine L-Aspartate (C4H7NO4C5H12N2O2) is characterized by an amino-acid-derived structure, an amide 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.

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.
