Description

Dl-7-Azatryptophan Monohydrate is a non-proteinogenic amino acid derivative of tryptophan, where a nitrogen atom replaces a carbon in the indole ring. This structural modification makes it a valuable biochemical tool and synthetic intermediate for research and development. It is primarily utilized by pharmaceutical researchers, biochemists, and fine chemical manufacturers. The compound is supplied as a monohydrate, indicating its stability in this crystalline form.

Application

• Biochemical Research: Acts as a key precursor or analog in the study of enzyme mechanisms, protein synthesis, and metabolic pathways.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of novel drug candidates, particularly those targeting neurological or metabolic disorders.
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis to incorporate modified tryptophan residues into peptide sequences for structure-activity relationship (SAR) studies.
• Metabolic Studies: Employed as a tracer or inhibitor in research focused on tryptophan metabolism and related biochemical processes.
• Academic & Industrial R&D: A fundamental reagent for universities and contract research organizations (CROs) exploring amino acid chemistry and biochemistry.
