Description

(2R)-2-[[[(1R)-1-Carboxy-2-Sulfanyl-Ethyl]Amino]Selanylamino]-3-Sulfan Yl-Propanoic Acid is a specialized organoselenium compound featuring a unique selenylamino bridge between two cysteine-like moieties, making it a critical reagent for studying redox biology and selenium metabolism. Its primary value lies in its ability to serve as a precise biochemical tool for probing thiol-disulfide exchange mechanisms and as a potential precursor in the synthesis of selenoproteins or selenium-containing pharmaceuticals. This high-purity compound is essential for researchers and developers in pharmaceutical R&D, biochemical research, and advanced material science, where controlled redox activity and specific molecular interactions are paramount.

Application

• Biochemical Research: Used as a model compound to study selenium's role in antioxidant enzymes like glutathione peroxidase, investigating mechanisms of action and catalytic cycles.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel selenium-based therapeutic agents targeting oxidative stress-related diseases.
• Proteomics & Peptide Synthesis: Employed in the site-specific incorporation of selenium into peptides and proteins for X-ray crystallography (phasing) and structural biology studies.
• Redox Biology Probes: Acts as a selective reagent or standard for developing assays that monitor cellular redox states and thiol-disulfide exchange dynamics.
• Nutritional Supplement Research: Investigated as a potential source of organic selenium in advanced nutritional and chemopreventive studies.
• Material Science: Explored for creating functionalized surfaces or polymers with specific redox-responsive properties.

Quality Control

Every batch of our (2R)-2-[[[(1R)-1-Carboxy-2-Sulfanyl-Ethyl]Amino]Selanylamino]-3-Sulfan Yl-Propanoic Acid is manufactured and analyzed under strict quality systems to ensure high purity and batch-to-batch consistency for research and development applications. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with exacting standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), it is recommended to store the product under an inert gas (e.g., argon or nitrogen) in a desiccated environment at -20°C or below for long-term stability. Keep the container tightly sealed in a cool, dry, and well-ventilated place away from incompatible materials.
