Description

Dnp-Dl-Glutamic Acid CAS NO 1655-48-7 is a chemically modified derivative of glutamic acid, where the amino group is protected by a 2,4-dinitrophenyl (Dnp) group. This modification is critical in peptide synthesis and biochemical research, where it serves as a key intermediate for protecting amino acids during complex molecular assembly. It is primarily needed by research institutions, pharmaceutical R&D laboratories, and fine chemical manufacturers involved in developing novel peptides, studying enzyme mechanisms, or producing specialized biochemical reagents.

Application

• Peptide Synthesis Intermediate: Acts as a protected amino acid building block in solid-phase and solution-phase peptide synthesis.
• Biochemical Research: Used in studies of enzyme kinetics, receptor-ligand interactions, and metabolic pathways involving glutamic acid.
• Pharmaceutical Development: Serves as a precursor or intermediate in the research and development of new therapeutic agents and diagnostic compounds.
• Organic Synthesis: Employed as a specialized reagent for introducing the glutamic acid moiety into complex organic molecules under controlled conditions.
• Reference Standard: Utilized as an analytical standard in chromatography (HPLC, TLC) for quality control and method validation in laboratories.
