(2,4-Dinitrophenyl)-L-glutamic acid CAS 4528-07-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2,4-Dinitrophenyl)-L-glutamic acid.

CATO supplies (2,4-Dinitrophenyl)-L-glutamic acid (CAS 4528-07-8), a certified reference material (molecular formula C11H13N3O8, MW 315.24 g/mol) for analytical method development and quality control.

The molecular framework of (2,4-Dinitrophenyl)-L-glutamic acid (C11H13N3O8) 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.

CATO manufactures (2,4-Dinitrophenyl)-L-glutamic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
