Description

Dnp-L-Isoleucine CAS NO 1655-56-7 is a chemically modified derivative of the essential amino acid L-Isoleucine, where the 2,4-dinitrophenyl (Dnp) group is attached. This modification is critical for advanced biochemical research and analytical applications, particularly in peptide sequencing and protein chemistry. It serves as a vital reagent and intermediate for pharmaceutical R&D, diagnostic kit manufacturing, and academic laboratories studying protein structure and function.

Application

• Peptide Sequencing Reagent: Used in Edman degradation and other methods for N-terminal amino acid analysis.
• Biochemical Research Intermediate: Serves as a key building block in the synthesis of specialized peptides and molecular probes.
• Pharmaceutical Development: Employed in the research and development of novel therapeutic peptides and metabolic studies.
• Diagnostic Kit Component: Utilized in the formulation of reagents for clinical diagnostics and enzyme activity assays.
• Protein Labeling & Modification: Acts as a tag or blocking group in studies of protein structure, function, and interactions.
• Academic & Industrial R&D: Essential for universities, contract research organizations (CROs), and biotech companies.
