Description

Seleno-D,L-Ethionine is a selenium-containing amino acid analog, where a selenium atom replaces the sulfur atom in methionine. This compound is of significant interest in biochemical and pharmaceutical research due to its role as a precursor for the synthesis of selenoproteins and as a tool for studying selenium metabolism. It is primarily utilized by researchers and manufacturers in the fields of life science research, pharmaceutical development, and nutritional science for applications ranging from metabolic pathway studies to the development of novel therapeutic agents.

Application

• Biochemical Research: Used as a key reagent in studies of selenium incorporation into proteins and enzymes.
• Pharmaceutical Intermediates: Serves as a building block for the synthesis of novel seleno-compounds with potential therapeutic activity.
• Metabolic Studies: Employed as a tracer or modulator in research on amino acid and selenium metabolic pathways.
• Nutritional Science: Investigated for its role and effects in selenium supplementation and bioavailability studies.
• Enzyme Inhibition Studies: Acts as an analog to study methionine-dependent enzymatic processes.
• Reference Standard: Used as a high-purity analytical standard in quality control laboratories for method development and validation.

Quality Control

Our Seleno-D,L-Ethionine is produced under a rigorous quality management system. Each batch is subjected to comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets the high standards required for research and development. Certificates of Analysis (COA) detailing specific results for each parameter are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
