Description

7-Nitro-Dl-Tryptophan Hydrochloride is a chemically modified derivative of the essential amino acid tryptophan, distinguished by the presence of a nitro group at the 7-position of the indole ring. This modification makes it a valuable synthetic intermediate and research chemical for probing biochemical pathways and developing novel compounds. It is primarily utilized by researchers and manufacturers in the pharmaceutical, biotechnology, and agrochemical sectors for applications ranging from medicinal chemistry to biochemical studies.

Application

• Pharmaceutical Research & Development: Serves as a key synthetic intermediate in the preparation of novel drug candidates, particularly those targeting neurological pathways or enzyme inhibition.
• Biochemical Studies: Used as a probe or substrate in enzymatic assays and metabolic pathway research to study tryptophan metabolism and related biological processes.
• Peptide Synthesis: Incorporated into custom peptides to introduce specific chemical functionality or to study the effects of nitro-aromatic modifications on peptide structure and activity.
• Agrochemical Development: Acts as a building block in the synthesis of advanced crop protection agents and plant growth regulators.
• Academic Research: Employed in university and institutional labs for fundamental chemical and biological research projects.
• Reference Standard: Used as a high-purity analytical standard for quality control and method development in analytical laboratories.

Quality Control

Our 7-Nitro-Dl-Tryptophan Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, to ensure it meets high-grade specifications suitable for research and development. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent degradation from atmospheric moisture.
