Chemical Structure

L-Lysine L-Glutamate CAS 5408-52-6 chemical structure

Description

L-Lysine L-Glutamate (CAS 5408-52-6), molecular formula C5H9NO4C6H14N2O2 and molecular weight 293.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of L-Lysine L-Glutamate (C5H9NO4C6H14N2O2) 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.
